Liquid X® Textile-based Force Sensors (FSRs)

Textile-based Force Sensors

Liquid X shunt mode FSR on nonwoven fabric

Liquid X custom designs and manufactures textile-based FSRs by printing its particle-free metallic ink directly on the textile substrate. Typically, FSRs are printed on multiple layers of sheet form PET (silver interdigitated fingers and then carbon layer). For textile applications, these layers of PET would be laminated together, then laminated onto the fabric requiring discrete wiring for connection to hardware.

With Liquid X’s textile-based FSRs, the particle-free metallic ink is deposited directly on the textile, enabling FSRs printed directly on the fabric. A printed carbon layer on flexible plastic is then laminated directly over the interdigitated fingers. Liquid X’s silver traces can be utilized as the circuit as well, eliminating the discrete wiring and reducing materials and steps in the manufacturing process while enabling durable force sensing technology directly on textiles.
