A secure and reusable medical patch for connected healthcare provides body temperature, oxygen saturation (SpO2) and heart rate monitoring over a secure Bluetooth® connection. This medical patch uses a rechargeable Li-ion battery for a small profile and enhanced reusability. An on-board battery charger uses a commonly available USB port for better charging accessibility.

System Benefits​:

  • MCU with integrated Bluetooth Low Energy (BLE) 5.0 for secure connectivity.
  • Optimized for low current consumption and longer battery life using a 20mAh flexible pouch battery.
  • High-accuracy temperature sensing (±0.5 °C).
  • Photoplethysmography (PPG) and proximity sensor for monitoring of essential bio data such as heart rate, respiratory rate, oxygen saturation (SpO2) with ±3.5% accuracy.
  • On-board Li-ion battery charger IC to recharge and monitor the battery with built in protection features.
  • Supports firmware updates via USB.

Target Applications:

  • Personal wearable health monitor
  • Medical health monitor
