Device and method for contactless skin treatment

摘要

Devices and methods for contactless skin treatment use feedback power control for non-invasive treatment of skin and human tissue. Electromagnetic energy heats skin or tissue. A feedback system measures an output physical quantity before the output of electromagnetic waves from the device into the patient. Alternatively the feedback system scans values of a physical quantity on or near the patient. The devices and methods allow for delivering the optimum amount of energy to the patient while reducing the thermal load of the device.

主权项

1. A device for contactless skin treatment by electromagnetic waves, comprising:
a power supply electrically connected to a high frequency generator and at least two electrodes; a sensor between the power supply and the at least two electrodes for measuring values of at least one physical quantity between different branches of symmetrical signal cables leading to each electrode and where input power to at least one electrode is adjusted based on the measured values.
