Printable on-chip micro battery for disposal bio-sensing device

[摘要] This paper reports an on-chip micro battery which can be fabricated on a CMOS chip. The battery consists of screen-printed Mg and AgCl films. An open circuit voltage of 1.58 V, the maximum power of 1.4 mW and a total stored energy of 400 mJ were obtained from anode and cathode electrodes of about 3 × 3 mm2. Demonstration devices self-powered by the on-chip battery worked in a 0.14 M NaCl solution, and digital data transmission from the devices using optical and electrical field methods were confirmed.
