该论文提出了一种由生物燃料电池供电的无线生理化传感系统，用于葡萄糖/乳酸检测。系统采用0.3V超低电压供电，集成了一个180nW、64dB SNR的被动ΔΣ ADC，解决了传统电池供电传感器体积大、寿命短的问题。
Itthipon Jeerapan, Joseph Wang, Patrick P. Mercier University of California, San Diego, La Jolla, CA Wearable physiochemical biosensors offer an exciting opportunity to monitor the concentration of ions and metabolites in bodily fluids such as sweat, saliva, and interstitial fluids for emerging applications in health and fitness monitoring [1]. However, current physiochemical sensing prototypes rely on batteries and DCDC converters to provide power for instrumentation, which may result in a large, obtrusive form factor with limited lifetime [1]. This paper presents a wireless physiochemical sensing system capable of monitoring glucose or lactate when powered via an enzymatic biofuel cell (BFC) based on energy naturally present in the underlying analytes to be sensed. Unlike prior-art BFC harvesters, which utilize bulky boost converters to increase the 0.3-to-0.4V BFC voltage to a higher level
