She’s fitted a piezo sensor on the bottom of each xylophone key, interfacing it with an Arduino. When a mallet hits a key the corresponding box augments the sound in one of several ways.

Quartz is a naturally occurring piezoelectric crystal that is widely used in oscillators, resonators, and sensors. Its piezoelectric properties, combined with its high thermal stability and low ...

PI’s P-562.6CD 6DOF Nanopositioning Stage uses parallel kinematics to achieve nanometer precision and millisecond response ...

These maintenance-free actuators, guidance systems, and sensors are highly durable and cost-effective, with no wear and tear. In NASA/JPL reliability tests for the Mars Mission, the actuators ...

The hysteresis is less than a nanometer. Ordinary piezoelectric translators are non-linear and exhibit hysteresis and creep. To overcome these deficiencies a position sensor is built into each DPT.
