Sensor Performs Non-contact ECG Measurements

The EPIC (Electric Potential Integrated Circuit) electric field sensor measures electric field changes without requiring physical or resistive contact. It can rapidly measure electric potential sources such as electrophysiological signals or spatial electric fields and promises to simplify the way medical ECG/EKG/EEG/EOG, movement sensing, proximity non-touch switching, or even gesture recognition signals are taken. The electrode surface of the detector is coated with a passivated thin dielectric for direct application to a test surface 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 EPIC sensor can also drive a relay to act as a simple non-touch electric switch. It can also be employed in a proximity mode or to detect specific kinds of movement as a gesture recognition device. SAELIG CO., Pittsford, NY. (888) 772-3544.
