Ultra-low cost EPIC sensor targets high volume consumer markets
EDN Staff - June 3, 2012
The PS25451 ultra-low cost version of the EPIC sensor provides remote sensing for high-volume consumer markets. A unique electrode design replaces the need for expensive titanium dioxide electrodes common in high-end medical applications of EPIC sensors.
The sensor measures tiny changes in an electric field similar to a magnetometer in a magnetic field, at a distance and through clothing. It can be used for security motion sensors and non-contact electrical switches, and medical applications. Adjusting the gain and bandwidth amplification circuitry, the sensors can be tuned for detection at a distance. Supplied in a custom 3D package with exposed pin, it measures 10mm x 10mm x 2mm. Production pricing is less than $1 in volumes above 50,000 units.
