Provided are wireless electronic devices for thermally interfacing with a biological tissue. The device may have a flexible substrate; a thermal actuator supported by said flexible substrate configured to provide a thermal input to said biological tissue; a temperature sensor supported by said flexible substrate configured to measure a temperature to determine thermal conductivity of said biological tissue; and a wireless electronic system in electronic communication with said thermal actuator and said temperature sensor, wherein said wireless electronic system is configured to provide two-way communication with an external controller. Also provided are related methods of using the electronic devices, including for cosmetic, beauty, or medical applications.

Wireless skin sensor with methods and uses

Flow sensor

Provided are conformable devices to measure subdermal fluid flow and related methods. A soft, stretchable and flexible substrate supports a thermal actuator and various specially positioned temperature sensors. A microprocessor in electronic communication with sensors calculates subdermal fluid flow from the measured upstream and downstream temperatures, as well as various application-dependent parameters. Devices and methods provided herein are particularly useful for measuring cerebral spinal fluid in a ventricular shunt placed for treatment of hydrocephalus.
