Fiber optic cable can definitely not be used as a sensor unless the path is physically broken, I use a lot of fibers at work and bending it has no effect. Photo resistors change resistance based on light level and lend themselves to a voltage divider circuit. So it could be used as some sort of opt...

Is it possible to use some form of piezoelectric to generate electricity during thrusting, massage, etc. in order to create a signal or produce power? If an electrical generating signal could be produced through movement and/or pressure that might solve a few issues by creating self reliant sensors....

If changes in light conductivity could be measured reliably optic cables could possibly be used in places such as lips where flexing would indicate movement on all axis. Limiting flexing to one axis might be difficult though and not sure if optic cables could be used as a variable pressure sensor. P...

Also we shouldn't forget about optical sensors. I'm thinking something like the flexible but semi-rigid milk white tubing with an LED in one end and a photoresistor in the other. As the tube bends the light level should vary, and so should the resistance. Nice, never thought of that. Definitely wor...

Another possible scenario would be passive materials (such as wire grids) in the doll body and a person wears the active sensors (similar to metal detectors) on the body such as wrists/hands/face/groin/etc. The size of the wire grid or simple wire (similar to an antenna) would possibly determine the...

Also there's the metal detector concept, one coil is effectively transmitting a frequency and another is receiving it, when a hunk of metal is near, the tuning of the coils is disrupted. So applying that to a pair of graphite embedded antennas I wonder if deforming the graphite would de-tune them i...

I've been testing some vaginal sensors using nitinol wire for a couple of years. I recently posted some pictures of how it's done, at https://github.com/ChristinesMan/ChristineAI/discussions/4#discussioncomment-9149592 Could you please explain how the nitinol wire is used as a touch sensor? Is it c...

Interesting articles on using graphene for sensors in artificial skin. https://www.inverse.com/article/29439-robots-solar-powered-charging-skin https://iopscience.iop.org/article/10.1088/1361-6528/aaa709/ampdf https://link.springer.com/article/10.1007/s40820-019-0302-0 https://www.mdpi.com/2079-4991...

Does the hair easily wash off when introduced to water? For example, when you're giving her a bath or a quick rinse? Just gave my companion a very hot shower with the credit card scrape for a deep cleaning. All hair stayed on (I was careful to work around the hair though) and the pubic hair looked ...

I have the Bluetooth with an antenna as well, was just illustrating an adapter. Bluetooth definitely has issues with lag, disconnection, range, connectivity to only one device at a time (which is very frustrating) but it can be used for the purposes described here. What would be a more satisfactory ...

Actually, I was hoping that the skeleton would be conductive from one end to the other. It could be used as the ground plane just like a car uses all the metal as the ground. That really wouldn't be too hard to test, a couple of sewing needles for probes to just puncture the skin and touch the mult...

There is soooo much potential here from someone who does animatronics! These could definitely be used for movable eyes in our companions. Would have to be modified for the space in the head but it could be done. I'm going to try and figure out a manual movement. As well on his Instructables site he ...

I'm actually getting ready to work with inductive charging for another product we're developing but it occurred to me a while ago how perfect it is for a doll. One thing I considered was a charging slipper. So the inductive pickup would be in her foot. A slipper that fits properly would ensure the ...

Hun just used hobby shop half marbles, no grinding needed. https://dollforum.com/forum/viewtopic.php?p=2459884#p2459884 I was looking at doing that before the marble idea but couldn't find anything that would fit. I'm glad you've shown it works. Using a ping pong ball as a base is much easier than ...
