Therapeutic Wearable Device
Overview
The Challenge
A smart wearable device was designed to offer users targeted heat therapy for pain relief. The primary challenge was to maintain precise temperature control while ensuring safety, responsiveness, and ease of use, whether locally or through a companion app. We developed the device around an ESP32 microcontroller, integrating multiple NTC thermistors for continuous temperature monitoring. A PID loop managed power delivery to the heating pad, maintaining the user's desired temperature consistently. BLE connectivity allowed seamless control via a mobile app, letting users adjust temperature and monitor real-time readings remotely. To complement remote access, the device also featured tactile buttons and a display for local control. Housed in a soft, wearable-safe enclosure with flexible PCBs, the device delivered a safe, intelligent, and comfortable heating experience that users could trust.
