E‐health monitoring using CSFH‐based mechanical sensors. a) Gesture recognition using 14 CSFH‐based mechanical sensors on every joint of a human hand. Color mapping of the variation in output resistance change, from the 14 CSFH‐based mechanical sensors, can be used for translation of the word “hydrogel”. b) Intracranial pressure (ICP) monitoring by placement of the CSFH‐based pressure sensor in the intracranial space. Upper panel: ICP at normal state and after euthanasia. Bottom panel: Real‐time monitoring of the ICP during an induced epileptic seizure. c) Speech recognition of the words of “ah,” “hello,” and “silk hydrogel”. d) Motion recognition of walking, jogging, and squatting.
