Signal specific electric potential sensors for operation in noisy environments
journal contribution
posted on 2023-06-08, 06:08 authored by S T Beardsmore-Rust, Robert Prance, Ahmet Aydin, H Prance, C J Harland, P B StiffellLimitations on the performance of electric potential sensors are due to saturation caused by environmental electromagnetic noise. The work described involves tailoring the response of the sensors to reject the main components of the noise, thereby enhancing both the effective dynamic range and signal to noise. We show that by using real-time analogue signal processing it is possible to detect a human heartbeat at a distance of 40 cm from the front of a subject in an unshielded laboratory. This result has significant implications both for security sensing and biometric measurements in addition to the more obvious safety related applications.
