Thermoforming Smart Orthoses via Metamaterial Structures for Body-Fitting and Component-Adjusting

2021-2022

ThermoFit is an end-to-end design and fabrication pipeline for thermoforming smart orthoses that adhere to clinically accepted procedures. ThermoFit enables the shapes and electronics positions of smart orthoses to conform to bodies and allows rapid iteration by integrating low-cost Low-Temperature Thermoplastics (LTTPs) with custom metamaterial structures and electronic components. Specifically, three types of metamaterial structures are used in LTTPs to reduce the wrinkles caused by the thermoforming process and to permit component position adjustment and joint movement. A design tool prototype aids in generating metamaterial patterns and optimizing component placement and circuit routing.
