A device and method for measuring the pressure exerted at different points of a flexible, pliable and/or extensible fabric capable of being worn as a garment, lapel, or the like, which provides three stacked layers including a first insulating layer comprising an arrangement of insulating fibers and at least one row of at least one conductive yarn in contact with a first surface of a piezoresistive layer of fibers of a piezoresistive material, and a second insulating layer comprising an arrangement of insulating fibers, including at least one row of at least one conductive yarn, in contact with a second surface of the piezoresistive layer, and an electronic circuit capable of measuring the electric resistance variation when a pressure is exerted on the fabric, the pressure being a function of the resistance variation.
A device for measuring the pressure exerted at different points of a flexible, pliable, and/or extensible fabric capable of being worn as a garment, lapel, or the like, characterized in that it comprises at least three stacked layers, the at least three stacked layers including a first insulating layer comprising an arrangement of insulating fibers, and comprising at least one row of at least one conductive yarn in contact with a first surface of a piezoresistive layer comprising fibers of a piezoresistive material, and a second insulating layer comprising an arrangement of insulating fibers, and comprising at least one row of at least one conductive yarn, in contact with a second surface of the piezoresistive layer, and an electronic circuit capable of measuring the electric resistance variation when a pressure is exerted on the fabric, the pressure being a function of the resistance variation.
A pressure sensor capable of being connected to an electronic circuit measuring the electric resistance variation when a pressure is exerted on the sensor, the pressure being a function of the resistance variation, characterized in that it comprises at least three stacked layers, the at least three stacked layers including a first insulating layer, comprising an arrangement of insulating fibers, and comprising at least one row of at least one conductive yarn in contact with a first surface of a piezoresistive layer comprising fibers of a piezoresistive material, and a second insulating layer comprising an arrangement of insulating fibers, and comprising at least one row of at least one conductive yarn, in contact with a second surface of the piezoresistive layer.
A method for manufacturing at least one pressure sensor capable of being connected to an electronic circuit measuring the electric resistance variation when a pressure is exerted on the sensor, the pressure being a function of the resistance variation, characterized in that it comprises at least the steps of:
