Abstract

Nano-thick epidermal electronics have extraordinary lightweight and conformability characteristics, thus enable high-quality signal acquisition and imperceptible wearing experience. However, reducing the device thickness to nanoscale makes the rigidity extremely low thus the device curls spontaneously, imposing unprecedented challenges to the device fabrication, handling and recycling. To resolve…
