According to this blog, PIP strongly resembles false-color images:
None of the sites promoting PIP offer peer-reviewed studies, show any
consideration of the possibility of such artifacts, or show evidence
of consistency of multiple scans taken with the client (after stepping
briefly away and back to the apparatus) in the same condition.
Whatever is different in the 'after' scan is invariably interpreted as
The simplest hypothesis: PIP is wishful interpretation of the brightness levels in a picture due to ordinary optics. I think its
appeal, like that of the Kirlian photography that preceded it, lies in
its gloss of objective science and its ability to produce an
attractive image that matches believers' expectations of what an aura
or energy field might look like.
From another article debunking PIP:
As usual with this type of pseudo-science, the proponents
unquestioningly accept the traditional physics, chemistry and medicine
that suits them, and reject the bits that don't.
I examined the photographs of Chakras ... and I noticed that the walls
of the room and the chair seem to have their own energy fields, very
similar to those of humans. This raises some questions:
o Does that mean that these inanimate objects are alive?
o Was the red congestion of the patient in picture one transferred to the back of the chair in picture three?
o Does the chair feel congested?
o Should we form a Society for the Prevention of Cruelty to Chairs?
If I didn't know better I'd think they were measuring minute
differences in temperature.
PIP only gives you a psychedelic false-color image from an ordinary photograph which is unlikely to show anything in the microwave range where cell-phones operate, so it would be unwise to rely on PIP as proof of the radiation-reducing properties of their chip.
Even if it did work, it would probably make things worse as @vartec commented.
