Arduino enthusiasts looking for inspiration for the next project may be interested in this new piece of hardware call the Caleiduino which takes the form of a digitally sound reactive Arduino ...

Abstract: This paper presents the performances of rainfall energy harvesting through the use of a piezoelectric transducer and an Arduino-based measuring system. Different studies agree on the ...

Piezo Trigger Switch circuit described here is a microcontroller-compatible shock/impact sensor switch module works on 5VDC supply. The whole circuit can be assembled on a 5×7 cm common circuit board.

The thinner our devices become, the less room there is for speakers and other thicker components. Kyocera has a solution, however: it just modified its Smart Sonic Receiver conduction technology for ...

Sporting a form-factor consistent with common piezo indicators, but generating roughly double the sound pressure, is how the company characterizes the KPI-800 family. The new 26-mm diameter by 22-mm ...
