The ESP8266 microcontroller is a favorite among makers for creating affordable, Wi-Fi-enabled sensor projects. Pairing it with a DHT22 temperature and humidity sensor is one of the easiest ways to get ...

The researchers have developed a new type of microbial fuel cell (MFC) that provides a reliable and constant source of ...

A US appeals court has found in favor of Masimo in its fight against Apple over pulse oximetry patents, but in the court that matters, a ruling makes it clear that there won't be another ban on the ...

Abstract: In this work, we present a single-pulse-driven micro flow sensor that features a wide measurable range, extended linearity, and fast response, which was realized by the synergistic ...

Abstract: The objective of this work is to implement and test an innovative single-unit multi-PPG measurement system to assess pulse transit time (PTT) measured between two sites on the forearm as a ...
