| Abstract Scope |
The future trends for wearable and implantable healthcare systems require a ceaseless power supply as certain medical condition, i.e., type 1 diabetes, require continuous monitoring and timely drug delivery. We demonstrate a true continuous healthcare system for type 1 diabetes by combining a low-energy micropump, self-powered glucose sensor, and ceaseless power supply based on thermoelectrics. 136.8 mJ (100%) of energy was acquired by charging a battery for 790.1 s using body heat harvesting. The micropump and sensor, each requiring 74.6 mJ (54.5%) and 25.3 mJ (18.5%), respectively, were successfully operated and the surplus 36.9 mJ (27.0%) was stored in the battery. Additionally, to continuously monitor the core body temperature (CBT), our recent efforts to build a compact vital band containing wearable sensors, unintermittent power supply, and flexible circuits located at a single location (the forearm) is presented. These findings can help realize a true continuous healthcare system in the future. |
