Thin-Film Electronics for Edge Intelligence: Gaussian-Sigmoid Transistors, Light-Driven Spikes, and Intelligent Risk Sensors
■講演の要旨
Emerging edge-intelligence applications require lightweight, adaptive hardware capable of local decision-making under uncertainty. This talk presents our recent efforts to develop intelligent and secure functionalities using thin-film electronic devices. Three platforms will be introduced: Gaussian-Sigmoid transistors for analog activation and hardware-level probabilistic inference; photo-spike photodetectors that convert light fluctuations into asynchronous electrical spikes for neuromorphic sensing and random-number generation; and UVC-based intelligent risk sensors for early fire detection and classification of fire types and potential causes. These studies demonstrate how tailored thin-film device physics can enable real-time sensing, probabilistic learning, and secure functionality in adaptive edge systems.
