Next generation of electronic devices will be not only flexible but also stretchable, enabling applications impossible to achieve with existing rigid circuit board technologies. This needs new materials and new design principles. In this talk, I will discuss the Monash e-skin-based wearable technology platform including the electronic skin materials using gold nanowires [1-3], ionic liquid [4] and bio-inspired design [5]. These materials can be used to fabricate high-performance wearable biomedical sensors enabling real-time monitoring artery wrist pulses, body motions and sporting activities in real-time and in-situ. Our sensors can communicate via smartphone, indicating the potential of remote health management anytime anywhere.
