i want to order prototype with tribo/piezoelectric propeties

[petrichor]

i want to order a prototype for a device that creates electric current from friction/pressure like by rubbing it with the hand. it also need to have EMG sensors.

i have no clue about who i should contact about it and i realy need some guidance here. there is a product i want to be made(as a prototype) and than to be tested by another person.

Hello and welcome.

I think a little more information about the project would be a good idea for us to make a suggestion.

Having some further knowledge of the application (don't ask), my recommendation is to first find some willing test subjects of the type that would be the "target" of this application. I would advise you to get their reaction to the impact, and whether or not it was appropriate. You would be advised to do some considerable research in this area prior to even contemplating a design.

I wish you success and your subjects much happiness...

At this point, there's no real need to close this thread, but I consider it would be a difficult one to conduct useful conversation without that need becoming more real.

finding a test subject isn't a problem. but before i find one i need a prototype to test.

so how do i find a service/person to build and/or design a prototype for me??. i realy need that question to be answered.

Do you know what voltage/current/waveform etc?

I suggest you have the cart before the horse if you're thinking of a prototype without knowing that.

find a few test subjects and see how they react. Have you tried this idea out on yourself? (naturally you'd not subject anyone else to this without trying it out on yourself).

And yeah, if I feel this thread should be closed I'll close it. Arguing with moderators is a great way of making that happen faster. At present I'll assume that English is not your first language and the tone of your PM was not intentional.

what "tone"? you mean this message to you?
"i hope you aren't realy considering to close my thread. i don't mentioned the purpose of the device and anyway my question was about "where to find somebody to build me a prototype"
and i don't have to actualy explain the purpose of the device for that" ? what was the problem with it?.

and how can i have test subjects if i don't have anything to test? i need someone who can design and/or build it.

have you actually explained to any possible test subjects exactly what you want to do to them ?
As Steve said, and I also knowing what you are planning, you yourself , should be your own first and foremost test subject !!
If you are unwilling to test on yourself, then you shouldn't even be considering using it on anyone else !!
There's no way on god's green earth that I would let you do that on me unless I knew you has personally tested it on yourself for some time

Petrichor,
These things have been around since the 60s...
Pier amusements had much larger "hang on" types.
The typical device was very simple though!!

the whole point of my comment was that my question is about having the device designed and builded and not about finding test subjects.

for the record i know many possible test subjects personaly, they are people who i talked to them about this device a lot and one of them actualy asked me about testing it if i manage to make it.
test subjects isn't the problem, the one and only problem is to have something to actualy test.

it works with battery or produce electricity from touch/pressure on it?
anyway i need the device to be in a custom shape and have more features in it like a sensor

 

[Martaine2005]

Actually, the originals were wind up, if I remember correctly..
You can probably still buy them with different circuitry that now uses a battery though..
A CR2023 or something like a watch or car remote uses.

i need something with custom shape and other different things. the device i am talking about have entirely different purpose.

it is reasonable to pay someone to make what i asked in my thread in his home? or it is too complicated for one person with electroinics knowledge to do in his home?

probably a local ( to you) electronics club something like that
you really need to be able deal with a builder in person, or at least have quick easy contact with

I have seen places on the net in days gone by that do that sort of thing

 

[Martaine2005]

It is entirely possible to make these in the home..
With a little homework, you could too.. No need to pay somebody!
In fact, I use one daily to get information from my children!!
Instead of a grunt, they actually talk!!!..

i think i look for electronic engineer on freelancer site. there is something in particular i should look for when i try to find someone to work with triboelectric and piezoelectric materials and EMG sensors?

 

[Martaine2005]

Absolutely.. Visit any site and ask for the chief Sado!!
He will answer all your questions and probably advise on a lot more current too!!

Good luck and keep us informed on your little project!
