DEVICE FOR MEASURING PRESSURE FROM A FLEXIBLE, PLIABLE, AND/OR EXTENSIBLE OBJECT MADE FROM A TEXTILE MATERIAL COMPRISING A MEASUREMENT DEVICE

摘要

The present invention relates to a device for measuring the pressure exerted at various points of a fabric that is flexible, pliable, and/or extensible and suitable for being worn as a garment, facing, or the like, characterised in that it comprises at least three stacked layers, a first insulating layer (1) produced from an arrangement of insulating fibres, comprising at least one row of at least one conductive thread (2) in contact with a first surface of a piezoresistive layer (3) consisting of a piece of fabric manufactured from fibres made from a piezoresistive material, and a second insulating layer (4), also produced from an arrangement of insulating fibres, comprising at least one row of at least one conductive thread (5), in contact with the opposite surface of the piezoresistive layer (3), and an electronic circuit suitable for measuring the variation in electrical resistance when a pressure is exerted on the fabric, the pressure being a function of the variation in resistance. The invention also relates to a pressure sensor suitable for being connected to an electronic circuit measuring the variation in electrical resistance when pressure is exerted on the sensor. The invention finally relates to a method for manufacturing a sensor according to the invention.
