Broadband, Flexible, Skin‐Compatible Carbon Dots/Graphene Photodetectors for Wearable Applications
Advanced Functional Materials, EarlyView.Broadband, flexible photodetectors integrating nitrogen‐rich carbon dots with single‐layer graphene on plastic substrates are demonstrated. A biocompatible chitosan–glycerol electrolyte enables efficient low‐voltage gating and on‐skin operation. The devices exhibit ultraviolet‐to‐near‐infrared response, mechanical robustness under bending, and verified

Trap‐Assisted Transport and Neuromorphic Plasticity in Lead‐Free 2D Perovskites PEA2SnI4
Advanced Functional Materials, EarlyView.An artificial retina built from lead‐free layered perovskite (PEA)2SnI4 converts light input into a persistent photocurrent and sums successive flashes over time. Micro/nanocrystals integrated on electrodes act as synapse‐like pixels that perform temporal integration directly in hardware. This in‐sensor preprocessing merges detection and computation on

Sensitivity to Mobile Phone Base Station Signals
Environmental Health Perspectives, 2008 Electromagnetic hypersensitivity (EHS) is a potentially highly significant public health problem. Eltiti et al. (2007a) recently concluded that short-term exposure to a GSM (global system for mobile communication) base station–like signal did not affect well-being or physiological functions in individuals, and they dismissed a positive reaction to UMTS
