摘要

<正>Bioelectronic devices work at the interfaces of biology and electronics. One of the most important targets of bioelectronics is to real-time monitor electrophysiological signals and metabolite of biofluids, including sweat, tear, saliva, interstitial fluid, etc. [1].These biosensors have contributed to a large part of the market in healthcare industry and their value is estimated to be US$13 billion annually [2]. Driven by the promise of the huge market,
