More Information
Summary:A biometric sensor includes a body surface sensor and an e-field signal transmitter. The body surface sensor create a drive-sense signal at a first frequency based on one or more sensing parameters. When operably coupled to a body via one or more electrodes, the body surface sensor provides the drive-sense signal to the body and detects an effect on the drive-sense signal based on electrical characteristics of the body. The body surface sensor generate a data signal based on the detected effect, wherein the data signal represents the body's electrical characteristics. The e-field signal transmitter generates an outbound signal reference at a second frequency based on the data signal and one or more transmit parameters. The e-field transmitter drives the outbound reference signal to the body, wherein the outbound reference signal is transmitted within at least a portion of the body as an outbound e-field signal at the second frequency.
