Figure 7. Performance of hydrogel as a sensor in physiological detection (A) the detection point is the masseter muscle, the thumb makes a “GOOD” gesture; (B) the detection point is the wrist, the hand makes a fist and slightly raises; (C) the detection point is the index finger joint, the finger is straightened to bent; (D) the detection point of hydrogel is the human throat; (E) the pharynx makes a swallowing motion; (F) vocalizing “a” [a:]; (G) vocalizing "A" "[ei]"; (H) vocalizing "Apple"; (I) vocalizing "Working".
