Title of Plenary Speech
A New Platform for Flexible Electronics: Exploiting Muscovite Mica
Heterostructures and Intercalation
Abstract of Plenary Speech
Muscovite mica is a layered silicate mineral that underpins MICAtronics, a
platform essential for developing flexible electronics. It has an atomically
flat surface after cleavage, enabling van der Waals heteroepitaxy, which is
highly beneficial as it accommodates large lattice mismatches (up to 60%) and
reduces epitaxial strain and substrate clamping. Mica shows high mechanical
flexibility and optical transparency, along with excellent thermal and chemical
stability. In this talk, I will first discuss the mechanical properties of
muscovite. Then, I will demonstrate how to modify muscovite's mechanical and
physical properties. The gaps within the mica structure act as two-dimensional
confined cavities, creating an intrinsic interlayer static pressure on inserted
materials (intercalants). This spatial restriction directs oriented growth,
making it possible to fabricate well-ordered 3D mesocrystals, including
superconductive MgB2,
antiferromagnetic NiO, ferromagnetic Fe3O4,
and Ag nanocrystals for SERS. Additionally, a new method for flexible crystal
growth will be shown through mobility and piezoresistive sensors. In the final
part of the presentation, I will focus on our recent advances in thermal
actuators and sensors.

Title of Plenary Speech
Abstract of Plenary Speech
With the growing demand for energy-efficient AI applications, the rapid
development of self-powered sensors together with edge computing and edge AI
technology at the sensor nodes has led to the new era of AI sensors. Traditional
sensors and sensing systems can no longer meet the demands for real-time
multimodal sensing and large-scale data processing, leading to a shift towards a
new paradigm of AI Sensors and Artificial Intelligence of Things (AIoT) sensing
systems with integrated computational intelligence. Self-powered wearable
sensors have promoted low-power or battery-free sensing platforms for
applications including human-machine interaction, soft robotics, and electronic
skin (e-Skin). Tactile sensors featuring artificial neuron like self-generated
zero-biased signals are developed to realize synergistic sensing of multimodal
information (vibration, material, texture, pressure, and temperature) in a
single device will be discussed first. On the other hand, aiming at smart
farming, various AIoT sensing systems have been developed recently. A
multifunctional hydrogel is developed as a stable energy harvester that
continuously generates direct current (DC) output with an average power density
of 1.9 W．m-3 for
nearly 60 days of operation in normal environments (24℃, 60% RH). Moreover, this
hydrogel enables non-invasive and self-powered monitoring of leaf relative water
content (RWC), providing critical data on evaluating plant health, previously
obtainable only through invasive or high-power consumption methods. The e-skin
sensors for indoor and outdoor farming applications will be discussed in this
talk as well.
In addition, the development of AlN/Si-based CMOS Photonics have been developed
as a near-sensor edge computing (NSEC) platform pushes the boundary of real-time
AI by combining electro-optic microring resonators (MRRs) and thermo-optic
interferometers (MZIs) to achieve low-latency neural computation directly at the
sensing layer. Demonstrated with high accuracy in multimodal gesture and gait
classification tasks (96.77% and 98.31%, respectively), and achieving latency
under 10 ns with energy consumption below 0.34 pJ, such platforms are paving the
way for privacy-preserving, always-on AI hardware for healthcare, robotics, and
immersive interaction systems. Overall, the fusion of AI-enhanced photonic
sensing, on-chip neuromorphic computing, and flexible sensor integration
represents a paradigm shift for future AIoT systems. As optical edge computing
continues to mature, it will become a cornerstone in the transition from
centralized cloud AI to energy-efficient, responsive, and context-aware edge
intelligence. Looking ahead, the convergence of AI, photonic integration, and
edge computing will catalyze the next wave of intelligent systems that are no
longer confined to centralized data centers or limited by power and latency
bottlenecks. Future AIoT architectures will evolve toward ultra-distributed
networks of smart, self-powered, and self-learning sensor nodes, each capable of
perception, inference, and adaptation in real time. Ultimately, the long-term
vision is a world where every object, environment, and human interaction is
seamlessly sensed, interpreted, and enhanced in real time.

Some Insights on PEMA-based Solid Polymer Electrolytes for EDLC Application
Abstract of Keynote
Speech
Electric double-layer capacitors (EDLCs) are promising energy storage devices
due to their high power density, long cycle life, and reliability. Polymer
electrolytes play a key role in their performance, and further improvements can
be achieved through suitable additives. In this work, poly(ethyl methacrylate)
(PEMA) solid polymer electrolytes incorporating sodium perchlorate (NaClO4)
and 1-butyl-3-methylimidazolium thiocyanate ([BMIM][SCN]) were prepared via
solution casting. The addition of [BMIM][SCN] enhanced amorphicity, polymer–ion
interactions, and thermal stability up to ~270 °C. The optimized composition
containing 25 wt% [BMIM][SCN] achieved an ionic conductivity of 3.15 × 10-4 S/cm
at ambient temperature. To further enhance performance, graphene was introduced
into the optimized electrolyte. The resulting EDLC exhibited a specific
capacitance of 5.09 × 10-3 F/g,
outperforming the graphene-free system. These findings provide insights into the
synergistic effects of ionic liquid and graphene in PEMA-based electrolytes,
highlighting their potential for advanced EDLC applications.

Low-Dimensional Materials: Synthesis, Characterization, Applications, and
Computational Studies
Abstract of Keynote Speech
Low-dimensional materials are fundamental semiconductor building blocks for
nanoelectronics and have attracted significant research attention over the past
decade. Non-volatile memory devices based on graphene quantum dots (GQDs) and
two-dimensional molybdenum disulfide (MoS2)
were fabricated and characterized. Current–voltage (I–V) measurements revealed
multi-stage bi-stable and tri-stable switching behaviors, demonstrating their
potential as two-terminal memory elements. The devices exhibited ON/OFF current
ratios with stable retention of up to 1 × 104 seconds.
Additionally, a ZnO nanorod-based field-effect transistor (FET) was developed as
a human serum albumin (HSA) biosensor. A TiO2-based interdigitated
electrode (IDE) amperometric biosensor was also fabricated for detecting HSA and
E. coli O157:H7. The TiO₂ nanoparticle platform enabled detection of HSA
concentrations ranging from 1 mg/mL down to 1 pg/mL. Multiple devices were
tested to assess stability, sensitivity, and reproducibility. After surface
cleaning, the sensors demonstrated reusability with consistent I–V profiles
across five devices, confirming reliable performance.
Computational studies were conducted to complement the experimental findings.
Molecular docking simulations were performed to analyze the structural and
electrostatic characteristics of the antibody–antigen interface. The results
confirmed that the APTES-functionalized TiO2 IDE
surface enhances antibody binding stability at pH 7, demonstrating the
effectiveness of the TiO2 platform
for biosensor applications. These findings provide preliminary validation of the
robust antibody immobilization on TiO2 surfaces.
Additionally, first-principles calculations were carried out to investigate
defects in various 2D and bulk materials. Structural stability, electronic
properties, and electron localization were systematically analyzed. Using
density functional theory (DFT), different phases of 2D SnGe2N4 were
evaluated for catalytic water-splitting reactions. The computed reaction
pathways and free-energy profiles indicate that SnGe2N4 is
a promising photocatalyst for the oxygen evolution reaction (OER).
Various synthesis and fabrication techniques for low -dimensional structures
have been developed to achieve high quality and low-cost production. One
promising approach is the synthesis of silicon nanowires using hot-wire chemical
vapor deposition (HWCVD) with an indium catalyst. In HWCVD, a heated tungsten
filament decomposes silane and hydrogen gases, resulting in high-crystallinity
silicon nanowires. The use of indium as a catalyst enables growth at relatively
low temperatures due to its low melting point (157 °C), compared to conventional
metals such as gold or copper. Key growth parameters, including catalyst size,
filament temperature, substrate–filament distance, and deposition time, were
optimized for improved nanowire formation. Subsequently, zinc oxide (ZnO)
nanostructures were integrated onto the silicon nanowires to form
three-dimensional heterostructured nanowires. ZnO was synthesized via vapor
transport condensation and hydrothermal methods. These Si/ZnO heterostructures
enhance the optical, photocurrent, and field emission properties of silicon
nanowires, overcoming their inherent limitations.

AIoT-Enabled Precision Diagnostics for Early Skin Cancer Detection: A Smart
Sensing and Deep Learning Approach
Abstract of Invited
Talk
The convergence of Artificial Intelligence (AI) and the Internet of Things (IoT)
is redefining the boundaries of precision healthcare by enabling real-time,
intelligent and patient-centric diagnostics. For early skin cancer detection,
AIoT-enabled precision diagnostic framework designed to bridge the gap between
clinical dermatology and smart engineering systems. The proposed architecture
integrates miniaturized IoT-based sensing devices including portable dermoscopic
imaging units and wearable skin sensors with a cloud-edge deep learning
platform. These devices continuously acquire high-resolution images and
physiological signals which are transmitted through secure IoT protocols to an
AI-driven precision analytics engine. The system employs convolutional neural
networks (CNNs) and attention-based fusion layers to automatically detect
segment and classify skin lesions into malignant and benign categories achieving
real-time inference and a communication adaptive learning. From an engineering
perspective, the system’s edge–cloud synergy, lightweight model optimization and
energy-efficient IoT design make it highly scalable and deployable across
healthcare ecosystems. By merging precision sensing hardware with AI-driven
decision models this research exemplifies the future of intelligent biomedical
systems where diagnostics evolve from static laboratory testing to continuous
connected and adaptive healthcare environments.

Abstract of Invited Talk
It is important goal to develop a renewable means to generate hydrogen for clean energy. One potential solution serves as a method of producing green hydrogen is known as photoelectrochemical (PEC) system. We demonstrate ferroelectric materials as photoelectrode for PEC water splitting, focusing on bismuth ferrite (BiFeO3) . One of the most remarkable features of BiFeO3 is the high ferroelectric polarization. We discuss the electrical interactions between a water-based electrolyte and BiFeO3, including the effectiveness of polarization switching procedure in a liquid environment, as well as the field-effect enhancement of water splitting performance with macroscopic spatial separation between anode and cathode.

Tailored 2D-MoSe2 Materials with Metal Dopants for Scalable Non-Enzymatic Biosensing Applications
Abstract of Invited Talk
Two-dimensional (2D) transition metal dichalcogenides (TMDs), particularly molybdenum diselenide (MoSe2), have emerged as promising materials for next-generation electrochemical and optical biosensing owing to their tunable band structure, high surface-to-volume ratio, and chemical robustness. Nevertheless, the intrinsic conductivity and limited surface reactivity of pristine MoSe2 necessitate further modification to enhance its sensitivity and selectivity toward specific biomolecules. In this context, MoSe2 nanostructures were doped with Ag, Au, and Ni in varying concentrations (0.5–5%) using a scalable hydrothermal synthesis approach. The structural, chemical and electrochemical characterization revealed notable modifications in charge transfer, and electrochromic response as a function of dopant type and concentration. Among the tested compositions, 1% Ag–MoSe2 exhibited superior non-enzymatic glucose sensing performance. Similarly, 2% Au–MoSe2 demonstrated excellent selectivity and sensitivity toward dopamine. Furthermore, 2% Ni–MoSe2 showed remarkable electrochemical response toward serotonin detection. These independent studies collectively highlight the potential of metal-doped MoSe2 nanostructures as versatile, multifunctional, and composition-tunable sensing materials. The findings provide critical insights into structure–property–function correlations and open new avenues for the development of scalable, enzyme-free, and cost-effective biosensors for healthcare diagnostics and environmental monitoring.
