Abstract

The invention discloses a flexible fabric switch, and belongs to the field of wearable electronic equipment. The flexible fabric switch comprises an upper conductive layer and a lower conductive layer, wherein an elastic isolation layer is arranged between the upper conductive layer and the lower conductive layer; one or more through holes are formed in the elastic isolation layer; and the upper conductive layer and the lower conductive layer are connected with conductive wires respectively. The flexible fabric switch is simple in structure; meanwhile, the upper conductive layer and the lower conductive layer can be in surface-surface contact for conduction; and in addition, the flexible fabric switch is light, thin and stable, and high in stability, fatigue resistance, bending resistance, and shearing resistance.

Description

technical field [0001] The invention relates to the field of wearable electronic devices, in particular to a flexible fabric switch applicable to smart textiles. Background technique [0002] At present, most of the switches used for switching are hard switches, and the parts for pressing are made of hard materials such as metal or plastic, so they will have a stiff touch when touched, and when used in various In different livelihood applications, especially when applied to clothing or other electronic products made of soft materials, this hard switch will produce an abrupt hard touch and gradually fail to meet people's needs. Therefore, in order to meet the demand, people have gradually developed soft-touch fabric switches, which can be applied to wearable electronic devices and smart textiles. At present, the upper and lower electrodes of these fabric switches are mostly connected through point-to-point, point-to-line or line-to-line contact. This structure has poor shea...
