Embodiment 1

[0051] The chewing gum that has been fully chewed for 20 minutes is thoroughly washed five times with deionized water and 75% ethanol respectively, and then stretched in a single direction for 100 times in a 6mol / L sodium chloride solution, and then sandwiched with VHB glue type package to build a capacitive smart sensor.

[0052] Such as Figure 4 shown, where as Figure 4 a The above figure shows the corresponding sensor capacitance change diagram when the eyebrows are raised on the face; Figure 4 The figure below a shows the capacitance change diagram of the sensor during the eye-closing process, and the internal map is the physical map during the experiment; Figure 4 b means that when drinking water, it can detect the movement of the Adam's apple, and the corresponding sensor capacitance signal changes, and the internal map is the physical map during the experiment; Figure 4 c represents the capacitive signal change diagram of the sensor attached to the elbow joint d...

Embodiment 2

[0054] The chewing gum that has been fully chewed for 20 minutes is washed thoroughly with deionized water and 75% ethanol five times respectively, and stretched in a single direction for 100 times in a 6mol / L edible saline solution, and then stretched with VHB glue. Sandwich packaging to build capacitive smart sensors.

[0055] Such as Figure 5 shown, where Figure 5 a indicates that the encryption principle involved in this chewing gum / refined edible salt smart sensor is based on the international Morse code encoding principle (that is, "one" indicates a long signal; "·" indicates a short and rapid signal), and the information is transcoded, and the original The text information is converted into electrical signals through the regular bending of fingers (it is stipulated that: 45°finger bending represents the "·" signal in Morse code; 90°finger bending represents the "one" signal in Morse code) (see Figure 5 b); and then through our pre-compiled translation comparison ta...

Abstract

The invention relates to an intelligent sensor for human health monitoring and information encryption transmission, which is obtained by performing sandwich type packaging on a chewing gum / sodium chloride compound through glue to construct a chewing gum-based capacitive intelligent sensor. The preparation process is simple, rapid, green, environmentally friendly and free of pollution, waste recycling can be achieved, and meanwhile the large-scale preparation capacity is met. The effective monitoring in various human motions can be achieved based on the chewing gum sensor, the chewing gum sensor can be further used for encryption, storage and transmission of important information, and a new thought is provided for preparation of intelligent wearable equipment.
