Pressure sensible textile and pressure sensible device thereof

摘要

A pressure sensible textile has at least a high-resistance conducting area and two groups of low-resistance conducting wefts or warps contacting the high-resistance area directly. The two groups of low-resistance conducting wefts or warps cross each other and do not contact with each other directly. Furthermore, two scanning circuits can be electrically connected to the two groups of low-resistance conducting wefts or warps. Then, a controller is added to the two scanning circuits to obtain a pressure sensible device.

1. A pressure sensible device comprising:
a main textile, comprising at least a high-resistance conducting area, wherein the high-resistance conducting area comprises a plurality of elastic high-resistance conducting wefts and warps, and a specific resistance of the plurality of high-resistance conducting wefts and warps is 102-106 Ω/cm, and wherein a breaking elongation of the elastic high-resistance conducting wefts and warps is greater than 30% so that resistance of the elastic high-resistance conducting wefts and warps varies as a deformation of the high-resistance conducting wefts and warps occurs, and the deformation is caused by a pressure source applied on the main textile; a plurality of first low-resistance conducting wefts distributed only over a first surface of the high-resistance conducting area and not interweaved with the main textile, wherein a specific resistance of the plurality of first low-resistance conducting wefts is less than 50 Ω/cm to conduct an electrical signal generated by the deformation of the elastic high-resistance conducting wefts and warps; a plurality of low-resistance conducting warps distributed and interweaved over the first surface and a second surface of the high-resistance conducting area, wherein the first low-resistance conducting wefts and the low-resistance conducting warps are separated by the main textile so that the low-resistance conducting warps do not directly contact the first low-resistance conducting wefts, and a specific resistance of the low-resistance conducting warps is less than 50 Ω/cm to conduct the electrical signal generated by the deformation of the elastic high-resistance conducting wefts and warps; a lateral scanning circuit comprising a plurality of first switches electrically connected to the lateral scanning circuit separately; a vertical scanning circuit comprising a plurality of second switches electrically connected to the vertical scanning circuit separately; and a controller connected to the lateral scanning circuit and the vertical scanning circuit, and being capable of turning on the plurality of first switches and the plurality of second switches alternately and repeatedly to receive the electrical signal such that a location and a magnitude of the pressure source can be determined by a data processing center.
