Technologies 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 a transmission electrode and receive biofeedback signals received by an electrode of the biofeedback monitoring device. The electrode contact analysis device is configured to process the received biofeedback signals to produce a received BCC reference signal from the received biofeedback signals and determine a quality of a contact between the electrode and the user based on the received BCC reference signal.監控在一生物回饋監控裝置之一或多個電極與使用者之間之接觸的技術包括電極接觸分析裝置。電極接觸分析裝置係配置以透過傳送電極傳送身體耦合通訊(BCC)參考信號及接收由生物回饋監控裝置之電極接收的生物回饋信號。電極接觸分析裝置係配置以處理接收之生物回饋信號以產生來自接收之生物回饋信號的接收的BCC參考信號,且基於接收的BCC參考信號來判定電極與使用者之間之接觸的品質。
