Article Synopsis
- Improving the lifetime and reliability of self-powered platforms is essential for practical applications, focusing on creating a battery-less wearable system.
- The designed system-on-chip (SoC) incorporates an ultra-low power (ULP) architecture, non-volatile memory, and efficient radio communication, all aimed at minimizing power consumption.
- With features like an energy harvesting power manager and a cold-boot management system, the SoC allows for extended operation without charging and capability for recovery from power loss.
This paper presents a batteryless system-on-chip (SoC) that operates off energy harvested from indoor solar cells and/or thermoelectric generators (TEGs) on the body. Fabricated in a commercial 0.13 μW process, this SoC sensing platform consists of an integrated energy harvesting and power management unit (EH-PMU) with maximum power point tracking, multiple sensing modalities, programmable core and a low power microcontroller with several hardware accelerators to enable energy-efficient digital signal processing, ultra-low-power (ULP) asymmetric radios for wireless transmission, and a 100 nW wake-up radio.
