I've been playing around with a couple of ESP32 microcontrollers, and that experimentation has taught me a lot about sensors and what you can build for really, really cheap. For as little as $4, you ...

Sensors that monitor infrastructure, such as bridges or buildings, or are used in medical devices, such as prostheses for the deaf, require a constant supply of power. The energy for this usually ...

Researchers have developed a battery-free sensor that reacts to sound waves, such as particular spoken words, producing enough vibrational energy to power an electronic device. The novel sensor would ...

IRVINE, Calif., Jan. 02, 2026 (GLOBE NEWSWIRE) -- AONDevices, Inc., a leader in super-low-power AI for audio and sensor intelligence, and InvenSense, a TDK group company and a global pioneer in sensor ...

Sensor fusion has been around for many years and is ubiquitous in mobile device designs. Sensor fusion “fuses” data from different types of sensors to improve measurement accuracy, such as for motion ...
