Printed Circuit Keyboard (1962)

The Printed Circuit Keyboard was designed in 1962. It was operated by the conductivity of the performer's finger using conductive material evaporated onto an insulator-backed sheet.

When the key was contacted, a small current was transmitted through the performer's finger from one conductive section to another. The pitch was amplified and played through speakers.
