June 2, 2012 - Saelig announces the PS25451, an ultra-low cost version of Plessey's EPIC Sensor that provides remote sensing for high-volume consumer markets. The PS25451's novel, economical electrode design eliminates the more expensive titanium dioxide electrodes currently used in higher-end medical applications. The EPIC Sensor (Electric Potential Integrated Circuit) measures electric field changes without physical or resistive contact. .
The PS25451 is an ultra-high impedance, non-contact, solid-state electric potential sensor that is ideally suited for a variety of consumer devices such as proximity switching of lighting, gesture-based remote control of interactive toys, computer games, TVs, monitors, other appliances, and presence detection - even through walls - for security/alarm systems. The EPIC sensor works by measuring tiny changes in an electric field in a similar way to a magnetometer detecting changes in a magnetic field even at a distance and through clothing. This enables it to be used for security motion sensors and non-contact electrical switches. The PS25451 is housed in a proprietary 3D package with exposed pins for surface-mount assembly, and measures 10mm x 10mm x 2mm.
By adjusting the gain and bandwidth of the associated amplification circuitry, the sensors can be tuned for detection at a distance as required. EPIC technology functions at normal room temperatures as an ultra-high input impedance sensor that forms a highly stable, extremely sensitive, contactless digital voltmeter to measure millivolt electric field changes. EPIC technology is so sensitive that it can detect human body movement at a distance or through a solid wall.
