ABSTRACT
Electronic skins (e-skins) have the potential to be conformally integrated with human body to revolutionize wearable electronics for a myriad of technical applications including healthcare, soft robotics, and the internet of things, to name a few. One of the challenges preventing the current proof of concept translating to real-world applications is the device durability, in which the strong adhesion between active materials and elastomeric substrate or human skin is required. Here, a new strategy is reported to embed vertically aligned standing gold nanowires (v-AuNWs) into polydimethylsiloxane, leading to a robust e-skin sensor. It is found that v-AuNWs with pinholes can have an adhesion energy 18-fold greater than that for pinhole-free v-AuNWs. Finite element modeling results show that this is due to friction force from interfacial embedment. Furthermore, it is demonstrated that the robust e-skin sensor can be used for braille recognition.
