Biodegradable nanofiber-based piezoelectric transducer

Significance This paper describes a powerful biodegradable and biocompatible piezoelectric nanofiber platform for significant medical implant applications, including a highly sensitive, wireless, biodegradable force sensor for the monitoring of physiological pressures, and a biodegradable ultrasonic transducer for the delivery of drugs across the blood–brain barrier. Built upon materials commonly utilized in medical implants, the devices can self-degrade, causing no harm to the body, and avoid any invasive removal surgeries.
