Abstract

A highly adaptive multi-sensor SoC comprising four on-chip sensors and a smart wireless acquisition system is first realized in standard CMOS process. To intelligently process different types (C/R/I/V) of sensor signals, a linear (R² = 0.999) and reconfigurable sensor readout is proposed. A two-input energy harvesting interface with conversion efficiency of 73 % is also integrated for long-term use. Experimental results show that four physiological parameters (temperature, glucose/protein concentration, and pH value) can be simultaneously monitored using this chip.
