Penile strain gauge

Anyone have experience taking in signal from a strain gauge like this?

I have a Seeed mounted on an Arduino Uno for other measures, so I would love a hardware solution that reads in to this setup. The other strain gauges I'm finding online are quite different types of strains gauges, so I am not sure their hardware would be appropriate:

Or are these appropriate?

You should contact Limestone to see if they have a technical datasheet for the device.

Aren’t those controversial? It used to be thought that orientation and desire were mutable, but that is no longer thought to be the case. Adversion techniques (think A Clockwork Orange) have fallen out of practice. I imagine there could be some ‘creative’ uses for a penile sphygmomanometer though.

OK, so that website gives no useful information.

A previous post on one of the forums here indicates that the resistance will be in the order of six Ohms, so you will want a single-supply op-amp which works with inputs down to the negative rail. Calibration is somewhat arbitrary, so precision and drift are not too much of a worry; it should not be too much trouble to set it up with the op-amp, grounding the strain gauge and feeding it via a 100 Ohm resistor to Vcc - the same Vcc which is the reference for the Arduino.

Sorry, that does not mean anything. :roll_eyes:


Controversial? He may simply be using it for NPT studies. Note the price tag on the female version though! :astonished:

There may well be safety issues around electricity and things tied ( in good contact with) to the body .

( eg power supply failure, shock or over heating of the strain gauge ?).

It may be a use for which Arduino is unsuitable ?

If you Google ( carefully) , these things were used in the US army to check for “ sexual orientation “ of new recruits in the 1950’s and were called “ Peter meters”.
I did some experiments with these but always broke the strain gauge

You were probably using one that was too small. The Limestone units go up to 110 mm diameter.

This is getting out of hand.

Yeah, sorry. The OP has not returned since their first post. Should it be closed?
