摘要： A unipolar power input type electromyography sensor is provided to be resistant to an electromagnetic wave and be stable by applying a signal to an electrode with being blocked from a common input voltage. A unipolar power input type electromyography sensor includes an electrode(10), a housing, and a circuit(4'). The electrode includes a reference electrode(1) connected to a ground wire, and a positive input electrode(2) and a negative input electrode(3) opposed to each other on the reference electrode. The circuit is incorporated in the housing to output a signal passing through the electrode after signal processing by filtering the signal. The electromyography sensor recognizes electromyography of an input through the positive and negative input electrodes and the reference electrode on the basis of an output of a differential amplifier(41'). A unipolar power input electrode is used as the reference electrode by separating the reference electrode from a ground and inverting the unipolar power input electrode in the differential amplifier.
