  A complete smart insole solution that continuously monitors the foot plantar
pressure and temperature can detect foot complications early and that too from
the convenience of the user home. Widespread health complications such as
Diabetic Mellitus need continuous foot complication monitoring to avoid severe
complications. With that motivation, this paper provides a detailed design of a
wearable insole using popular off-the-shelf sensors to monitor foot plantar
pressure and temperature. The design provides details of which temperature and
pressure to be used, circuit configuration for characterizing the sensors, and
the considerations for developing a compact Printed Circuit board design using
appropriate microcontrollers and communication protocol. The system also
provides details of how the foot pressure and temperature data from the
subjects using the sensors can be transferred wirelessly using a low-power
consuming communication protocol to a central device where the data will be
recorded. The investigation can help in developing a low-cost, feasible and
portable foot monitoring system for patients by facilitating real-time, home
monitoring of foot condition using Gait Cycle or Foot Pressure patterns and
temperature heterogeneity between two feet. The proposed system will work in
real-time.
