Abstract
A muscle activity observation apparatus that includes a sensor module and a detection module. The sensor module includes a piezoelectric sensor. Moreover, the piezoelectric sensor has an output that changes in accordance with a tremor of a tendon or a muscle, and an output that changes in accordance with contraction and relaxation of the tendon or the muscle. A detector of the detection module detects an activity state of the tendon or the muscle using a tremor signal and a contraction-relaxation signal output from the piezoelectric sensor.
