Heat transfer equation
Heat transfer equation
(OP)
Dear follow engineers.
I need your kind help.
I have a device which emits rf energy when touching the skin.
Because of this energy, the tissue heats up.
Now, there are 2 options:
1. If I place a non conductive lotion on the skin (high impedance), and then apply the rf energy, most of it will develop power on the layer beneath the skin, hence fat, as current prefers to flow through a lower impedance.this is like heating a resistor.and its dissipation time till cool down usually takes longer as its "locked" beneath the skin.
2. If I place a conductive lotion low impedance, most of the energy will be developed on the skin surface.however, since the upper skin tissue role is to evacuate heat much faster, I believe that the degradation rate would be faster than point 1.
My question, can someone help me with proving it mathematically using a heat transfer equation or else? It's been 30 years since college days....
Thanks

Link RF is used as a cauterizing and tissue reduction technique for conditions like sleep apnea; I've had that done to myself, but to no avail
Link Link RF is known to cause repairable tissue damage that forces reconstitution of the collagen and other support tissues for firmer skin, etc. Different frequencies penetrate differently, and have differing results. No RF fat reduction, so far as I know, and there are already too many competitors in that arena anyway,
As alluded to by chicopee, there is a large swath of literature on both subjects.
