Biofeedback electrode contact monitoring technology

摘要

Techniques for monitoring contact between one or more electrodes of a biofeedback monitoring device and a user include an electrode contact analysis device. The electrode contact analysis device is configured to transmit a body-coupled communication (BCC) reference signal via the transmitting electrode and receive a biofeedback signal received by the electrode of the biofeedback monitoring device. The electrode contact analyzer processes the received biofeedback signal to generate a received BCC reference signal from the received biofeedback signal, and based on the received BCC reference signal, the quality of the contact between the electrode and the user Configured to determine.
