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 method and system for calibrating a measurement from a shoe-based sensor device for measuring pressure at one or more parts of a shoe sole and providing at least one pressure sensor measurement signal indicating the measured pressure, the method being performed at a processor that receives the at least one pressure sensor measurement signal and including: determining a minimum value for the at least one pressure sensor measurement signal and storing the determined minimum value as a correction constant in a data memory associated with the processor; and correcting a value for the at least one pressure sensor measurement signal received subsequent to the step of storing, by the stored correction constant.

Abstract: A senor insert for a shoe includes a flexible planar portion having a shape of an inner sole for a shoe. The flexible planar portion includes a central layer containing a plurality of pressure sensors for sensing the pressure applied by the foot and electrical connections to the sensors; a lower layer having a lower face arranged to face the sole of a shoe and having a first coefficient of friction; and an upper layer having an upper face via which a foot is arranged to impact the insert and having a second coefficient of friction which is lower than the first coefficient of friction.
