[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 ...

In this device, [Kerry] found that a long, narrow piezoelectric element spans the long axis of the sensor, suspended from what appears to be four flexible arms. [Kerry] probed the innards of the ...

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 ...

A piezoelectric motor contains a ceramic element that, when given an electrical signal, produces force on a ceramic plate in a specific direction. This interaction drives the rotor, creating an ...
