[Jason] has continued to plug along with his sonar build and recently showed up a monostatic active sonar using a piezo element and microphone. Regular readers will remember [Jason’s ...

Clearly, the little cans aren’t going to make very much sound on their own, but with a piezo speaker element used in reverse, the cans become touch sensors that feed an Arduino and drive a MIDI ...

The operating principle is based on coordinated motion of a number of highly preloaded linear and shear piezo elements acting on a runner and does not involve rotation/linear conversion. The working ...

The slow rise segment (A) expands the piezo element, and then the rapid drop (B) contracts the piezo suddenly, overcoming the static friction between it and the moving component. Speed of inertial ...
