Abstract: Devices, systems, and, methods for measuring deformation variation in an insole to determine characteristics of a user, including weight and gait, are described herein. In some embodiments, a device includes an insole having a fluid reservoir configured to be disposed in a shoe, a deformation sensor, and a communications module. The fluid reservoir includes a first portion and a second portion. The deformation sensor is coupled to the fluid reservoir and is configured to measure a deformation in at least one of the first portion and the second portion. The communications module is configured to receive the measured deformation from the deformation sensor and transmit the measured deformation to a remote device.

Abstract: Apparatuses, devices, and methods for measuring pressure are described herein. In some embodiments, a device includes an insole configured to be disposed under a foot of a user during use. The device further includes a fluid reservoir formed at least partly within the insole, the fluid reservoir containing a fluid. The device further includes a sensor fluidically coupled to the fluid reservoir and configured to sense an indication of pressure in the fluid reservoir during use. The device also includes a communications component communicatively coupled to the sensor and configured to receive the indication of pressure from the sensor. The communication component is further configured to transmit pressure information associated with the indication of pressure to a remote device.
