Abstract
Smart touch sensors, leveraging human body communication technology, are innovative devices designed for lifelog collection, but their power consumption poses significant design challenges due to their battery-powered nature. This brief highlights the necessity for a one-chip design solution following an analysis of the limitations in existing devices and pioneers the development of the first touch-based lifelogging processor. The developed processor achieves superior low-power performance through the introduction of cutting-edge voltage scaling technology that exploits the characteristics of ultra-low voltage operating circuits and the development of network-on-chip supporting plug-in style clock gating technology. Fabricated using a 28nm FDSOI process, the processor demonstrates a peak power consumption of just 3.33mW and 0.23mW in standby, extending the lifetime of the smart touch sensor device by 7.5 times.
