Wireless optofluidic systems for programmable in vivo pharmacology and optogenetics
Provided are implantable, injectable and/or surface mounted biomedical devices and related methods for interfacing with a target tissue. The devices have a substrate, one or more microfluidic channels embedded in or supported by the substrate and a fluid actuator in operational communication with one or more reservoirs and responsive to a wireless control signal. The components of the device are specially configured and packaged to be ultra-thin and mechanically compliant. In some embodiments, the devices are self-powered and fully implantable. 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.
