Thrust IV: Integrated Sensor Node Design and Prototyping
THRUST IV is charged with integrating technologies and components from research thrusts I-III into a complete electrical prototype of a wearable self powered system. This prototype will be ready for packaging and test bed deployment in Thrust V. The heart of the ASSIST node will be a System-on-Chip (SoC) integrated circuit that includes power management and delivery, sensor front end circuits, digital processing and storage, and a radio.
GOAL: Develop integrated sensor node(s) with:
- Power < 30 μW (excluding sensors) for energy harvesting, and
- Instantaneous peak power during RF transmission <200 μW.
- Severe power and energy constraints
- Numerous independent parts, options, and design teams
- Heterogeneous technologies
- Subthrusts: System design and optimization; Low power computation; Low power communication; Multiscale modeling
- Cross thrust integration: system modeling; careful interfacing; block level co-design
- Leverage prior work in ultra low power SoCs, such as below:
