Polymer strain gage does away with wires
Extremely sensitive to slight pressures, a small deformation to the paste generates a change of its electrical resistance generating an analogue signal to enable measurement, input and control to a wide range of applications. As the strain gage can be directly printed on the application’s control board, it does not need to be connected by wires. This enables compact and affordable designs, as well as eliminating the failure points of wire failure and corrosion. It also eliminates electrical sparking as the key contacts come together.
Interesting applications include musical instruments such as a piano keys and electric guitars, control switches for DJ audio mixing gear, inside shoes to measure pressure distribution as someone stands or walks, for use in “silent” keyboards (no key clacking), inventory control for grocery store shelves and vending machines, automotive touch screens and function activators, as well as hazardous area applications where a tiny spark from keys closing an electrical circuit could set off a fire or an explosion.
The new P-DMS Strain Gage is available in wide variety of customized sizes and shapes.
