Abstract

The invention discloses a fabric-based capacitive sensor, which comprises an electrode layer a and an electrode layer b, a fabric dielectric layer is arranged between the electrode layer a and the electrode layer b, and the electrode layer a , the electrode layer b and the fabric dielectric layer are all cured and encapsulated by the encapsulation material, and both the electrode layer a and the electrode layer b are connected with wires. The invention also discloses a manufacturing method of the above-mentioned fabric-based capacitive sensor. Firstly, pre-treat the fabric dielectric layer, then immerse the fabric dielectric layer in the dispersion liquid and take it out after ultrasonication; print the mold through a 3D printer, and convert the conductive The copper foil is pasted on the surface of the fabric dielectric layer, then placed in the mold, and the mold is clamped; after the packaging material is prepared, it is poured into the mold, and after standing still, the above mold is placed in a curing furnace for curing treatment, and the final product Fabric-based capacitive sensors. The invention solves the problems of poor flexibility and high manufacturing cost of the existing capacitive sensors.

Description

technical field

[0001] The invention belongs to the technical field of flexible wearable electronic devices, relates to a fabric-based capacitive sensor, and also relates to a manufacturing method of the capacitive sensor. Background technique

[0002] Smart textiles are a kind of textiles that highly integrate electronic technology and fabrics. In addition to maintaining the basic functions of traditional textiles, they also have functions such as monitoring, information processing and communication. It has broad application prospects. Smart textiles are generally composed of sensors, actuators, data processing, communication, and power supplies. Sensors are the key for smart textiles to realize the interaction between the human body and the outside world, which requires the sensors to have good flexibility, high sensitivity and fast response. Traditional sensors are mostly composed of metals and semiconductors, and have poor coupling with fabrics. After direct integration...
