We operated a Hall sensor using energy harvested from a magnetic wire. A batteryless sensor is expected to be a key device for the Internet of Things. Magnetization reversal in magnetic wires with ...

This paper investigates influences of Hall sensor magnetism on the torque performance of a slotless permanent magnet (PM) brushless dc (BLDC) motor through two-dimensional finite-element method (2-D ...

Thus, they entered a heart rate sensor to our 2025 One Hertz Challenge! The build is based around a Wemos D1 mini, a ESP8266 development board.
