Embodiment Construction

[0034] The present invention is described in further detail below in conjunction with embodiment.

[0035] figure 1 The illustrated embodiment shows the manufacturing process of the skin tactile sensor involved in the present invention, including the following steps:

[0036] (1) Cut the natural cellulose fabric and / or the regenerated cellulose fabric into cloth pieces 1 of suitable size, and iron them flat;

[0037] (2) Draw a square on the cloth piece 1;

[0038] (3) Carry a smaller square along the inner circle of the square with silver-plated yarn 2;

[0039] (4) The silver-plated yarn reserves a length of 10 cm on one side of the cloth piece 1 as the wire 3;

[0040] (5) Apply conductive composite material 4 to the front of the cloth block 1 (the side without the silver-plated yarn wire 3), then cover with a semicircular raised part, a mold 5 with a radius of about 1mm, and compact it ;

[0041] (6) After forming by natural vulcanization at room temperature for 24 ho...

Abstract

The invention discloses a skin touch sensor. The skin touch sensor comprises a flexible base layer and a conductive composite material layer, wherein a plurality of groove structures are arranged on the conductive composite material layer; and the skin touch sensor is characterized in that the relevant coefficient of voltage and pressure of the skin touch sensor is formed by steps of placing sensors on the skin on the inner side of a human arm, then connecting the sensors with a Mind Ware multi-guide physiological instrument, next carrying out repeated cyclic compression experiment data collection on the sensors with different sizes through a universal material testing machine INSTRON, and then carrying out data fitting. The invention further discloses a preparation method of the skin touch sensor. The skin touch pressure sensor provided by the invention has the beneficial effects of being combined with any textiles to prepare the skin touch pressure sensor capable of measuring the small pressure, so that the defect that the skin touch sensor is only suitable for high pressure measurement is overcome; and in addition, the skin touch sensor can be directly worn and directly attachedto skin of the surface of a human body, and can be used for testing the pressure borne by the human body in static or dynamic states.

Description

technical field [0001] The invention belongs to the technical field of electronic materials, and in particular relates to a skin tactile sensor and a manufacturing method thereof. Background technique [0002] The measurement and analysis of tactile pressure distribution are widely used in many fields. Flexible tactile sensors can be used to monitor various contact pressure distribution information related to human health and safety. The current research on haptics is gradually deepening, especially the development of flexible tactile force sensor technology, which has created various new tactile application fields including manufacturing, service industry, medical treatment and entertainment, and is more and more suitable for virtual reality in various industries. system. For example, in terms of medical devices, for medical devices such as colonoscopes that are in direct contact with the patient's organs, flexible tactile sensors can be covered on the surface of the devi...
