Injectable and implantable cellular-scale electronic devices

Abstract

Provided are implantable or surface mounted biomedical devices and related methods for interfacing with a target tissue. The devices have a substrate and device component supported by the substrate. The components of the device are specially configured and packaged to be ultra-thin and mechanically compliant. In particular, device thicknesses are less than 1 mm and have lateral dimensions between about 1 m and 10 mm, depending on the application. Delivery substrates may be incorporated to assist with device implantation and handling. The devices can be shaped to provide injection in a minimally invasive manner, thereby avoiding unnecessary tissue damage and providing a platform for long-term implantation for interfacing with biological tissue.
