Abstract: A physiological signal recognition apparatus and a physiological signal recognition method are provided. A root mean square algorithm is executed on a physiological signal to obtain a noise threshold, and the physiological signal is adjusted based on the noise threshold to obtain an adjusted signal. Then, a muscle strength starting point in the adjusted signal is detected.

Abstract: An electronic device for signal interference compensation is provided. The first signal line is electrically connected to the transmitter. The second signal line is electrically connected to the receiver and coupled with the first signal line. The electrode is electrically connected to the second signal line and measures a physiological signal. The processor is electrically connected to the transmitter and the receiver, and configured to: transmit, via the transmitter, an active signal to the first signal line; receive, via the receiver, a coupling signal corresponding to the active signal from the second signal line, and calculate a compensation value according to the coupling signal; and receive, via the receiver, an interfered signal corresponding to the physiological signal, and restore the physiological signal according to the compensation value and the interfered signal in response to the compensation value matching the interfered signal.

Abstract: A physiological signal sensing and compensation system is provided, for contacting an object to be measured and sensing a physiological signal. The physiological signal sensing and compensation system includes a physiological signal sensing module, a compensation module, and a computing unit. The physiological signal sensing module provides an initial sensing signal. The compensation module includes a collecting mechanism for collecting a physiological liquid of the object to be measured. The compensation module provides a compensation signal according to the physiological liquid collected by the collection mechanism. The computing unit is electrically connected to the physiological signal sensing module and the compensation module, and calculates and provides a compensated sensing signal based on the initial sensing signal and the compensation signal.
