Touching the strips determines which notes will be played. A piezo disc hiding below the circuit board detects how hard the notes have been strummed or tapped. The ATmega328 running the ...

Piezoelectric materials are unique substances that generate an electric charge in response to applied mechanical stress. They are widely used in various applications, including sensors, actuators ...

We wondered if a piezoelectric disk would work. We are looking forward to seeing a homebrew robot based on this technique. We have seen other wall climbing robots, of course. Some can even fly.

BENGALURU: Scientists have discovered that making piezoelectric ceramics — used ... “By replacing a 1mm ceramic disc that has 0.3% strain with five 0.2mm discs stacked on top of each other ...
