Problems solved by technology

Because the upper and lower layers are a non-integral structure (stacked), when the pressure deformation of each layer structure is greatly different, it is easy to cause the upper and lower electrodes to be misaligned, resulting in local upper and lower electrodes that may not be able to conduct, especially when the pressure and sensor area are large This phenomenon is especially evident when
At the same time, this also increases the manufacturing process, and the production cost is high.

Abstract

The invention relates to a fabric sensor for pressure distribution monitoring. The fabric sensor comprises warp yarns and weft yarns. The warp yarns and the weft yarns are arranged in an orthogonal manner. The crossed warp yarns and weft yarns together form an induction area and a connection area. The head end of each row of the warp yarns in the connection area is connected to a power supply end,and the head end of each row of the weft yarns in the connection area is connected to a collecting end. The induction area is formed by induction units which are arranged in a staggered mode. Each induction unit is arranged in a sandwich-shaped structure, wherein the upper layer and the lower layer of the induction unit are respectively in the form of a positive electrode layer and a negative electrode layer, and the middle layer of the induction unit is in the form of a conductive layer. The positive electrode layer and the negative electrode layer of each induction unit are both composed ofa plurality of conductive yarns and non-conductive yarns. The conductive yarns of the positive electrode layer and the conductive yarns of the negative electrode layer are not adjacent to each other.The conductive yarns of the positive electrode layer and the conductive yarns of the negative electrode layer are orthogonally arranged. The conductive layer is composed of resistance yarns and non-conductive yarns. According to the invention, a positive electrode can be conducted with a negative electrode through the conductive layer with the presence of a compressed and large-area sensor. Therefore, the monitoring accuracy is ensured.

Description

technical field [0001] The invention relates to a fabric sensor, in particular to a fabric sensor for pressure distribution monitoring. Background technique [0002] Pressure sore is one of the most serious clinical nursing deficiencies. Once a pressure sore occurs, it will not only bring pain to the patient, aggravate the condition, prolong the recovery time of the disease, and even endanger life due to sepsis caused by secondary infection in severe cases. Preventive care for pressure ulcers is very important. [0003] The most important cause of pressure sores is that local tissues are under continuous vertical pressure. Therefore, real-time monitoring of pressure magnitude and distribution can help medical staff understand the pressure on local body tissues of patients in various postures in real time, so as to take corresponding nursing measures to help Patients reduce stress, ease pain, reduce the chance of exacerbation of the disease, and shorten the recovery time of ...
