Right - so if I get a TENS or your E-stim (series 1 or 2), I mustn't use it above the waist? I thought TENS units were designed to be used primarily above the waist?[/quote]estim_si wrote:With TV programs Health and Safety is a key issue. The units should not be used above the waist, nor by people suffering from eplisy, heart conditions (pacemakers) and pregnacy.

The above the waist guidence is more don't pass current across the chest. stating don't play above the waist covers many different positions that could compromise this. hand to hand for instance. a number of TENS units have little or no safety warnings, and some are also designed to be used under strict medical supervision. We also state playing with E-Stim whilst pregnant is not a good idea, but TENS is used for pain relief during pregrancy. We have to err on the side of caution.
It's a very simplistic view (the parallel resistor view is related to Kirchoffs Voltage law) The human body is a very complex entity when it comes to current flow, and even more so when you are considering nerve response modelling. Variable resistance, impedence and a number of other active factors all come into play.birdbundy wrote:Another thing about the below-the-waist safety rule: would I be correct in saying electricity sees the body as a lot of parallel resistors? So if you apply electricity to (for example) the foot, that will actually go through the heart - but just a little - due to the resistors in parallel equation?
If it's a case of nipple to nipple then there is a risk. However remember that many websites protray activites that don't actually take place due to safety. For instance the cattle prods used on a well know site are known to be modifed to reduce their levels to within safe margins. Remember just because you have seen it on film or a website it doesn't mena it actually happened exactly as seen. Commercial companies want to make good imageery, not open themselves to various lawsuits.birdbundy wrote:I've seen "electric clothes pegs", where a TENS-like unit (actually the extremely-expensive EROSTek) has been wired to a wooden clothes peg. This is often placed on a nipple. Is this really completely dangerous?
Although we haven't done tests directly on breast tissue, fat has a different level of conductivity to muscle mass. Frequency of the simulation waveform is a core factor (as it the waveform shape) in achieving optimium stimulation, but the frequencies of stimulation are far lower than 300MHz by several levels of magnitude, and the skin effect is only really relivent to strong simple conductors. It is a misnomer that the skin effect has any relation to electrostimulation or even the use of violet wands.birdbundy wrote:I mean, female breasts don't conduct that well because of the fat, and the nipple is so sensitive that the amount of electricity that would cause stimulation should be small. If the frequency of the electric current is high enough it shouldn't affect the heart beat and the skin-effect should offer some protection too (though that requires 300 MHz or more to really make a difference with human tissue)?
We have know people to play for 10's of hours. In that case the issue is with contact points drying out, and numbness creeping in. If it start to feel uncomfortable, then stop.birdbundy wrote:What kind of time-scale is it safe to use for?
No as we are using AC waveforms, where the net charge transfer is zero. DC based stimulation does cause issues, this is why most of the major manufacturers of E-Stim equipment, ourselves included use AC biphasic wafeforms.birdbundy wrote:Is the human body electrolysing an issue?

Originally I was looking at the Series 1 box... but then I also the ABox, and as Series 2 does both (and some more) it seems like the logical choice. Also - I don't know if any of your boxes or attachments do this - but have you thought of having a zzzap noise to do with the electricity?
In terms of noise It has been mentioned, but for most people the fact the boxes don't make any noise (they might buzz slightly under heavy loads) is a bonus. The Series 2 is a good choice.
Personally I don't have any experience with it, and therefore cannot comment.birdbundy wrote:Another question - have you heard of the TAZapper? If so, what's your opinion of it? There's always been quite a lot of talk about contiuous current toys like TENS, but capacitor-discharge electricity is rarely discussed (intelligently).
