Soft Wearable Electronics Based on Metal Nanowire Network
Soft electronics takes a leap beyond Si-based rigid electronics. They are made of ultrathin, compliant, and stretchable materials, already with broad applications from personal health monitoring to prosthetics to human-machine interfaces. Metal nanowires, in particular silver nanowire (AgNWs), have emerged as a promising soft electronic material. In this talk, I will discuss the recent advances in AgNW-based soft electronics. I will start with highly conductive and stretchable AgNW electrodes, followed with a variety of wearable sensors for monitoring of human physiology and motions (e.g., strain, pressure, temperature, hydration, ECG, and EMG) and wearable heaters including their integration with textiles. I will discuss their applications in personal healthcare and sports. Manufacturing is a critical enabling step towards large-scale applications. I will present scalable and sustainable nanomanufacturing of AgNW-based soft electronic devices. I will conclude the talk with our recent efforts in thermally actuated fast and programmable soft robotics.
