Abstract: A battery-powered multisensor acquisition system with five dedicated channels [electrocardiograph (50 μW), bioimpedance (46 μW), galvanic skin response (15 μW), and 2× photoplethysmogram ...

A miniaturized driver manages red, green, blue, and white LEDs for maximum impact with minimal system CPU burden.

The post examines reverse-phase dimming, also known as trailing-edge dimming, commonly used in modern lighting systems.

Abstract: Photonic wire bonding is demonstrated to enable highly efficient coupling between multicore fibers and planar silicon photonic circuits. The technique relies on in-situ fabrication of ...
