Finally, they showed that when the circuit was deposited onto a polymer substrate, its performance remained stable even when bent to a radius of 15mm – confirming its flexibility. Thanks to these ...

The circuit’s main components comprise amplitude detector D 1, capacitor C 1, and Schmitt trigger Q 1 /Q 2 to control a current through the optocoupler’s LED. D 2 and D 3 stabilize the base voltage of ...

Following is a transcript of the video. Narrator: Have you ever wondered how these bands of lights come together? It's a simple string of miniature light bulbs, with some wiring inside that ...
