Fully gravure printed wireless cyclic voltammetry tags

For the first time, fully gravure printed wireless cyclic voltammetry (CV) tag is reported as a platform for the disposable wireless sensor tags by utilizing Ag nano-particle based conducting ink, BaTiO₃ nano-particle based dielectric ink and single-walled carbon nanotube based semiconducting ink. The printed CV tag contains four functional units for the disposable wireless sensor tag: the rectenna to generate polarized DC volt through coupled 13.56 MHz AC, triangle wave generator to scan electrochemical cell by ±500 mV at lower frequency (<; 500 mHz), amplifier to enhance the output signal and signage to indicate detected level of specimens. Those printed four units will be used as a platform to further develop disposable wireless sensor tags by simply replacing sensor unit.
