The human is with high mobility, and from human motion, information related to physical and mental health, lifestyle, and gait performance could be extracted. Since most human motion is performed with both feet, we designed a Smart Insole system for foot motion measurement.
To meet the requirement of clinicians on measuring accuracy and comprehensiveness, up to 96 pressure sensors were uniformly distributed on the pressure sensor array to ensure a high spatial resolution for the measured plantar pressure, and an Inertial Measurement Unit (IMU) was used to measure foot acceleration and angle.
The feedback from manufacturing partners indicates that building different Smart Insoles for different foot sizes would significantly increase the manufacturing cost. To decrease the cost and ensure a good fit, we proposed a customizable design method which makes it possible for the pressure sensor array to be trimmed to fit different foot sizes. For the present prototype, the customizable pressure sensor array makes it possible for the Smart Insole to be trimmed to fit foot sizes from 5.5 US to 14 US.
Since people prefer sensors embedded into their clothing or accessories than wearing a technology separately, we proposed an unobtrusive design method for the Smart Insole. All the necessary hardware, including sensors, circuit board, and battery, were embedded into an insole shaped package to make the Smart Insole looks and could be used the same as a regular insole.
