Abstract
A system and a method for detecting a muscle activity are provided. The system includes a vibration sensor. The vibration sensor detects a vibration signal at a sensing point located at an opposite side of an operating muscle system for analyzing a body movement.
Claims13
A muscle activity detection system, comprising:
- a wearable ring, having a central point, a first extension line and a second extension line, wherein the first extension line and the second extension pass through the central point and are substantially perpendicular with each other;
- a first vibration sensor, located at a first antagonistic muscle group corresponding to a first agonist muscle system to detect a first vibration signal of the first agonist muscle system for analyzing a body movement, wherein the first antagonistic muscle group and the first agonist muscle system locate two opposite sides of a body region, the first vibration sensor is fixed on the wearable ring, and only the first vibration sensor is located at the first extension line;
- a second vibration sensor, located at a second antagonistic muscle group corresponding to a second agonist muscle system to detect a second vibration signal of the second agonist muscle system for analyzing the body movement, wherein the second antagonistic muscle group and the second agonist muscle system are located on two opposite sides of the body region, the second vibration sensor is fixed on the wearable ring, and only the second vibration is located at the second extension line;
- and
- an analysis circuit, analyzing the body movement at least according to the first vibration signal and the second vibration signal;
- wherein passes through the first antagonistic muscle group and the first agonist muscle system, the second extension line passes through the second antagonistic muscle group and the second agonist muscle system and crosses the first extension line, only one vibration sensor is located on the first extension line being the first vibration sensor, and only one vibration sensor located on the second extension line being the second vibration sensor.
