Abstract: A force sensitive resistor includes first and second electrical contacts, and a layer of deformable material impregnated with carbon nanotubes. The layer of deformable material is arranged between the first and second electrical contacts. A difference in the conductivity of the impregnated material caused by deformation of the material is detectable across the contacts. A method of manufacturing a force sensitive resistor includes the steps of providing first and second electrical contacts, and arranging a deformable material impregnated with carbon nanotubes between the first and second electrical contacts. Again, a difference in the conductivity of the impregnated material caused by deformation of the material is detectable across the contacts.

Abstract: A sealed force-sensitive resistor is provided. The sealed force-sensitive resistor includes: a bottom layer; a first conductive element attached to the bottom layer and a top layer. The top layer is sealed to the bottom layer in an airtight manner. The force-sensitive resistor further comprises a spacer ring surrounding the first conductive element and a flexible top sensor layer. The top sensor layer is attached across the spacer ring and comprises a second conductive element facing the first conductive element.

The force-sensitive resistor further comprises an air permeable spacer material between the top and bottom layer.

Abstract: A force sensitive resistor is provided comprising: a flexible bottom layer of a first material, comprising a first conductive element attached to the bottom layer; a spacer ring attached to the bottom layer, the spacer ring surrounding the first conductive element and extending away from the bottom layer; and a flexible top sensor layer of a second material attached across the spacer ring comprising a second conductive element facing the first conductive element. The flexible top sensor layer is moveable relative to the flexible bottom layer to vary the resistance of the force sensitive resistor. The Young's Modulus of the first material is less than the Young's Modulus of the second material. The flexible bottom layer extends past the spacer ring. The foregoing arrangement locally limits the amount of flexion of the lower layer in the region surrounding the first conductive element, thereby ensuring accurate data can be obtained.
