P-DMS Polymer Strain Gage from Hoffmann + Krippner enables compact and affordable designs

The P-DMS Polymer Strain Gage from Hoffmann + Krippner is a compact and cost-effective solution for measuring pressure. The device is based on sensor paste technology on a PCB board. 

Extremely sensitive to slight pressures, a small deformation to the paste effects a change of its electrical resistance, generating an analog signal to enable measurement, input, and control in a wide range of applications.  Requiring no moving parts, this simple device can be very accurate and long-lasting. Because 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 and eliminates the failure points of wire failure and corrosion.  It also eliminates electrical sparking as the key contacts come together. 

Applications include musical instruments, such as piano keys and electric guitars; control switches for DJ audio-mixing gear; inside of shoes to measure pressure distribution as someone stands or walks; use in “silent” keyboards (no key clacking); inventory control for grocery store shelves and vending machines; automotive touch screens; function activators; and hazardous area applications, where a tiny spark from keys closing an electrical circuit could set off a fire or an explosion.  

The P-DMS Strain Gage is available in a wide variety of customized sizes and shapes and is available for shipping.
