| الوصف: | A highly adaptive multi-sensor SoC comprising four integrated on-chip sensors and a smart wireless acquisition system is realized in standard CMOS process for the first time. To intelligently process different types (C, R, I, and V) of sensor signals, a linear (R-square is 0.999) and reconfigurable sensor readout is proposed based on switched-capacitor circuit technology. In addition, a dual-input energy harvesting interface with conversion efficiency of 73% is also integrated to pick up light energy and RF power, which potentiates long-term use without battery replacement. The entire SoC occupies die area of 11.25 mm 2 and consumes only 942.9 μW. Experimental results show that four physiological parameters (temperature, glucose and protein concentration, and pH value) can be simultaneously monitored using this chip. This system can be seen as a universal sensor platform. Different types of sensors can be easily integrated into it for convenient use, which dramatically reduces time consuming of building a new sensor system. |
