Medical applications of radio frequency (RF) energy, in the form of electromagnetic waves (radio waves) or electrical currents, have existed for over 125 years, [1] and now include diathermy, hyperthermy treatment of cancer, electrosurgery scalpels used to cut and cauterize in operations, and radiofrequency ablation. [2]
In this situation, a simple probe type sometimes called an RF detector can be used to convert the RF signal to DC. Such device will work as a RF rectifier and give a pulsed DC voltage. [2] The second kind of difficulty arises when RF energy has to be measured in a circuit which is sensitive to small changes in its electrical environment.

Radio-frequency (RF) engineering is a subset of electrical engineering involving the application of transmission line, waveguide, antenna, radar, and electromagnetic field principles to the design and application of devices that produce or use signals within the radio band, the frequency range of about 20 kHz up to 300 GHz.
This is a list of emerging technologies, which are in-development technical innovations that have significant potential in their applications. The criteria for this list is that the technology must: Exist in some way; purely hypothetical technologies cannot be considered emerging and should be covered in the list of hypothetical technologies ...
Examples include an identifying integrated circuit RFID device encased in silicate glass which is implanted in the body of a human being. This type of subdermal implant usually contains a unique ID number that can be linked to information contained in an external database, such as identity document , criminal record , medical history ...

The ETSI formalized the proposal into a standard called MEDS (with the core MICS bands remaining under that name and the new "wing" bands being referred to as MEDS) in December 2007, [3] while the FCC added the same additional spectrum to MICS and dubbed the expanded plan the Medical Device Radiocommunications Service or MedRadio in May 2009.
