A The schematic drawing of the as-prepared microfluidic solid-state pH sensor. The yellow color on the silicon wafer stands for gold patterned microelectrode by photolithography.

The wearable uses a pH sensor made from graphite-polyurethane composite, stretchable radio-frequency-identification (RFID) antenna, and a flexible data transmission printed circuit board (PCB).
