the beauty of RF - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.

click link to see what RF means to the beauty industry, its energy, how lovely.
Does anyone know what sort of power / frequency do these things run at ? any ideas ?

And a snip at only €490 = $636 !
And you thought the military had good margins..

So that's why we all look so svelt and beautiful: all that radiation does wonders for our skin tone after standing in front of a few hundred watts of VHF.
From what little I have seen of portable diathermy devices they push out a few tens of milliwatts, and operate at a few MHz. I have seen some pain relief type devices operating at kHz frequs though, but very little power.
So the spin is: don't be scared about EM Radiation: it's good for you. Have some more.

"What is Radio Frequency?
 
Radio frequency in the context of aesthetic beauty, is a general method to heat deep skin layers by delivering electrical current via poles/electrodes to the body, in order to tighten and rejuvenate skin, or reduce cellulite or pockets of fat."

Greetings Guys:

I looked at the website, and while they do have some cool pictures of a "tripole," I have to be a bit skeptical. :roll:

I wonder if there has ever been a study done that shows people have nicer skin in areas where their cellphones are stored and used? If the frequency used happens to be in one of the cell bands, then there should be a lot of people walking around with beautiful ears, hips, and thighs. :wink:

There is at least one legitimate use for RF therapy other than x-rays for cancer treatment. Melanie had been suffering with acid reflux for many years, and back around 2003, she underwent a treatment called a Stretta® Procedure. It was a relatively new treatment at the time.

With it, a probe with retractable RF pin probes is inserted in the esophagus, into the region of the lower esophageal sphincter (just above the stomach opening. RF energy (I asked the doc, and he wasn't sure of the frequency) is blasted into the muscle with the result being that over a few months time the collagen in the area shrinks in reaction to the local heating.

This website has a animation of the procedure
http://www.reflux1.com/video/LibraryStr ... mation.swf

It worked for a couple years, but a hernia at the top of the stomach lining was still causing a problem, and limited the effectiveness of the Stretta, so she ultimately underwent a procedure where the surgeon wraps the top of the stomach around the lower esophageal sphincter to physically reduce its diameter so that the muscle can close the opening. Incomplete closure is what allows the acid reflux to occur.

So far, so good. I only went into the gory details in case someone reading suffers from GERD or LPR (which was Melanie's malady) and is desperately seeking treatment.

I really haven´t found any convincing arguments regarding the usage of this technology for this application.

What i do know is that there are RF-scalpels ... :)

Newbee here. Just enjoying your post when I came across your medical application of RF. As it turns out, I have a couple of other applications.

One was for the treatment of prostrate growth. The company packed three spiral antennas along with three optical fibers within a catheter. As I recall, the antennas were driven around an ISM frequency at 2.? GHz and the fibers were doped suct that they flouresced at the tips (inside the patient) and the wavelength of the flourescence changed with temperature. Hence the patient had three temperature regulated microwave heaters in him.
The story was that lack of blood flow in the prostrate would cause it heat more than the surrounding tissue, causing some tissue to die and be reabsorbed by the body.

The other app was much simpler, and I know it's still in use.
Essentially, a 3-1/2 in "pancake" coil and a couple of mica capacitors form a tank that rings at about 2 MHz. These are part of a simple Collpits oscillator keeps a couple of amps circulating though the coil. The resulting B field is strong enough to power / charge a medical implant that is located under the skin. So, a goodly few people are walking about with 25mW transmitters tapped to their bellies.

And you forgot about pigeons becoming eagles when flying near airport radar antennas... :mrgreen:
