Here’s a fun build from [RootSaid] that is suitable for people just getting started with microcontrollers and robotics — an Arduino-controlled two-wheeled robot. The video assumes you already have one ...

China’s microelectromechanical systems (MEMS) sensor industry is surging, but technical gaps, fragmented production and coordination challenges hinder its full potential. As global demand accelerates, ...

Optical sensors are a broad class of device for detecting light intensity. This can be just a simple component for notifying when ambient light levels rise above or fall below a prescribed level, or a ...

Abstract: A proposed chest patch device and its interface IC are configured to allow detection of multi-domain signals in the form of optical, electrical, acoustic, and chemical signals at a single ...

Photoplethysmography (PPG) is a widely used non-invasive technique for monitoring cardiovascular health and various physiological parameters on consumer and medical devices. While motion artifacts are ...

Abstract: In this study, we developed a miniature wireless in-ear device for bio signal monitoring. The device is based on a flexible printed circuit board (FPCB), allowing it to be folded or deformed ...
