Wearable health monitoring with stretchable nanogenerators

NanoWerk.com - Mon, 12/04/2017 - 16:48
So far, most of the developed self-powered piezoelectric devices are rigid or have limited lateral stretchability and could not be used to harvest energy from lateral strain, which greatly limits their applications on large strain deformation. In new work, researchers have successfully fabricated a piezoelectric nanocomposite device with good transparency, high stretchability, and self-powered sensing characteristics. Attached to the human body, it can harvest biomechanical energy and monitor physiological signals.
