The fine print: towards wearable electronics

Skin-like or epidermal electronics that can adhere seamlessly to human skin or even within the body are highly desirable for applications such as health monitoring, medical treatment, and biological studies. The scope of this kind of technology extends to others including human-machine interfaces, soft robotics and augmented reality. There has been tremendous interest in rendering such electronics soft and stretchable in order to make them more comfortable to wear. Wearable sensors that continuously monitor and communicate vital health data, such as temperature, heart rate and blood pressure, to name a few, could help prevent diseases and monitor chronic conditions reducing healthcare cost. Furthermore, these sensors would be able to provide large amounts of health data possibly helping to accelerate clinical trials and scientific research. However, technical challenges, such as the fabrication of high-performance flexible/stretchable sensors and memory modules that are in intimate mechanical contact with skin or soft tissue, limit the wide-scale adoption of such systems. Conformal electronics with increased contact area would therefore greatly enhance the quality of signals acquired from/through the skin. This talk presents recent advances in additive manufacturing techniques, whereby functional nanomaterials can be directly "printed" to create devices for wearable electronics.
