This is an interesting concept, however, I don't think that the ECG/EMG is the best way to do the sensing.
THere are some links and alternative ideas discussed in the forums on another site:

IMHO, a plethysmograph is probably the best way to go. (Don't let ...

Just wanted to tell everyone that I did some more experimenting :-)

As stated previous and done in my earlier experiments, the penile plethysmography indeed has the ability to detect the circumference changes during pubic muscle contractions. The indium-gallium gages are indeed very sensitive ...

Greetings all,

http://www.Fetlife.com (a site I really enjoy) is giving away some interesting toys.
Check it out!

Thanks for pointing this out tool out; I'll start marking the spam posts.

(that actually makes good sense, now that I think about it.)

That's an interesting idea. There've been discussions of a sensor (penile plethysomograph) where a cock ring would go, but I hadn't thought of using it to restrict blood flow, much less have it automatically adjust. Hmmm... Doing the adjustment pneumatically is one way, but maybe something like a ...

As Jabber mentioned, the vendor apparently isn't selling the induim/gallium gage outside the US.

[/quote] The range went from 1.1 Ω to 1.3 Ω. So to turn this into a device that is useful for our purposes, we simply need to create something that can measure resistance fairly accurately within that range and that can be hooked up to a computer. Can't be too difficult, can it?

Problem is that ...

Just a question of quriosity... When you're about to cum and your muscles contract, how much do the Pascal alter?

Unfortunately I am not that much into anal play, so my testing was rather quick and I was not near cumming. But I could see the effect of squeezing the buttplug.

But I guess there ...
