WS2 Optoelectronic Memristive Reservoir Enabling Ultra‐Low‐Power, Multi‐Task, and Environmentally Stable Neuromorphic Computing

Advanced Science, EarlyView.
WS2‐based in‐memory sensing reservoir computing integrates sensing, memory, and computation in one compact device. It achieves ∼94% N‐MNIST, ∼93% eye motion perception, and ∼89% speech recognition with ultra‐low energy (∼25.5 fJ/spike). The system shows stability at 95% humidity, endurance over 1.5M cycles, and supports synaptic plasticity, enabling ...

(In)visible light communication

ACM SIGGRAPH 2014 Emerging Technologies, 2014
Consumer devices transform into interactive communication interfaces when visible light is used to transmit data. At home, during work or leisure time, light bulbs, toys, or other electronics and accessories can be used as environmental sensors, and act as user interfaces based on their location, play pattern, or other context provided by the Internet.

Precoded visible light communications

2013 9th International Conference on Information, Communications & Signal Processing, 2013
Multiple input multiple output (MIMO) technology appears attractive for indoor visible light communication (VLC) systems as multiple light-emitting diodes (LED) sources are typically deployed for indoor environment. Most of current indoor MIMO VLC systems utilize single user terminal scenario to investigate the performance of the system.
