Abstract
A controller for sensing deformation including a sensor structure having a deformable conductor and another conductor (which may also be deformable). The deformable conductor may be made out of a flexible non-fluid material (e.g., rubber) or a conductive fluid. The deformable conductor may be deformed by the deformation of the sensor structure or by other forces. The sensor comprises circuitry to drive and sense signals on interacting pairs of conductors (the deformable conductor or the other conductor can act as the drive side, or as the sense side). Sense signals are processed to analyze deformation of the deformable conductor, and deformation of the sensor structure. Where the sensor is deployed proximate to human skin, deformation and changes in deformation may be used to correlate or infer a body position, movement or pose.
