INTRODUCTION

Recently, stretchable electronics have attracted much attention due to their abilities to sustain complex deformation and conformal contact with irregular surfaces, which meets the demand generated by the rapid development of electronic skins and wearable devices [1- 3]. In order to make the devices stretchable, new materials synthesis and special structure design are two important areas of development [4]. Many nanomaterials, such as carbon nanotubes [5], graphene [6] and metal nanowires [6-9], have been used to fabricate stretchable electronics with polymers [4,10]. Some novel structures, including wave, mesh and textile, are applied in the device designs [4]. There is a spectrum of promising applications for stretchable electronics, for example, sensors, energy harvesters, displays, smart skins, health monitors and wearable electronics, which would facilitate our lives in many ways [1-10]. Human or robotic motion detection is indispensable for human-machine interfaces, next-generation prosthetics and healthcare monitor [3,11]. Some strain sensors based on nanomaterials have been developed to achieve wearable detection [5,7,9]. However, one weakness of majority of current wearable sensors is need for external power source, which means indispensable wire connections, limited usage time and the need to be recharged very often and makes the sensing system bulky [11,12]. The other is that the transparency of the sensor has been severely weakened in some cases [5-9], which is inconvenient to integrate with other sensors. Ag has the highest electrical conductivity among all the metal materials, and silver nanowires (AgNWs) networks shows a high transmittance for a wide range of wavelengths [4], which make AgNWs attach much attention for potential applications as transparent, flexible and stretchable electrodes [6-9]. Here, through prestretching and spin-coating, AgNWs are distributed on the polydimethylsiloxane (PDMS) membrane surface uniformly and form a conductive and transparent network, which is still stable and recoverable even after thousands of stretches. When attached on human skin or prosthesis directly, the sensor could catch the motion signal based on triboelectrification and electrostatic induction in real time [11-14], and detect static gestures by strain-resistance response of the AgNWs network. PDMS-AgNWs structure makes the sensor stretchable, transparent, wearable and self-powered.
