Saelig Introduces Non-contact Electric Field Sensor

By DE Editors

Saelig released the EPIC (Electric Potential Integrated Circuit) electric field sensor. The sensor measures electric field changes without requiring physical or resistive contact.

The electrode surface of the detector is coated with a passivated thin dielectric for direct application to a test surface (such as human skin) without the need for electrically conductive gel. It can be used as a dry contact ECG sensor without the need for potentially dangerous low impedance circuits across the heart. By detecting changes in the electric field, the sensor can also drive a relay to act as a simple non-touch electric switch. It can be employed in a proximity mode or to detect specific kinds of movement as a gesture recognition device.

According to the company, applications include electrophysiological signal detection, ECG/EKG/EOG/EMG/EEG non-critical patient monitoring, emergency response diagnostics, sports and health products, electric field and potential sensing, movement sensing, security, switching and gaming applications, etc.

Epic Sensor Demo Boards, made by Plessey Electronics, are available through Saelig.
