I am not an electrical engineer but an industrial designer, and I work for a SexTech company that strives to create sophisticated sex toys for women.

We are currently trying to prototype a vibrator that can sense the pressure applied to it. We have been trying conductive fabric, usual FSP sensors and non of them work to what we need.

I was wondering if anyone can direct me or help out with what sort of sensor can be used to this case. I know it's been done by other companies for different cases, for example by Lioness (youtube unboxing video).

  • \$\begingroup\$ they are not a competitor since what we are doing is totally different, and unfortunately their product is not available for purchase on this part of the world \$\endgroup\$ – Aydan Jan 12 at 19:01
  • \$\begingroup\$ I'm surprised you can't find an exporter from the US. Probably means you're in a sanctioned country, i.e. Iran, Burma, Ivory Coast, Syria or North Korea. In either country, you get my fullest respect for selling sex toys for women, considering government ideas of decency or safety situation. \$\endgroup\$ – Marcus Müller Jan 12 at 19:11
  • \$\begingroup\$ Yeah, find a "parcel forwading service" order on-line and send it the forwarders, then pay them to have it delivered to you. \$\endgroup\$ – Jasen Jan 13 at 9:32

From the top of my head:

  • The thing is probably hermetically sealed anyway. So, if you make the hull compressible, you can simply use an air pressure sensor, as used e.g. in blood pressure measurement. Air pressure sensors are cheap and reliable.
  • the product video you've linked to makes it suspiciously much look like there's discrete points that are pressure sensitive. Don't overestimate the smartness of that; might simply be microswithches behind "springy" pieces of plastic. If it's very intensely engineered, there might be a simple load cell or stress sensor.
