Abstract

Inkjet-printing was used to prepare a flexible and transparent humidity sensor with a Ti3C2/Ag hybrid as the humidity-sensitive film and poly(diallyldimethylammonium chloride) (PDDA) as the adhesive layer. The sensor demonstrates an ultrahigh sensitivity (106 800%), a rapid response (80 ms), and excellent bending resistance. We demonstrate that an array of sensors can track moving fingers in a non-contact way and map the distance of the fingers away from the sensor surface. Therefore, our humidity sensors have great potential for novel human–machine interfacing such as touchless control of electronics and collision control between robots and humans in a cobot setting.
