A few folks have been wondering where we're at on the Bionic Dildo, as we've taken to calling it.

We've made a lot of progress in the last few months, starting with setting up a workspace for research, development, and testing. We've moved into the new space, where we have a lot of resources we didn't have before.

The first few prototypes were put together by modifying existing sex toys. This crude approach was good enough to show us that the basic technology is sound, but the prototypes we built this way were limited, fragile, and rather uncomfortable to wear.

Since then, we've acquired a 3D printer and facilities for making ceramic molds to cast silicone. This allows us to create custom-designed silicone with electronics, sensors, and electrodes cast right in.

From 3D rendering to printed positive that we use to make a mold.
And yes, those are Lego bricks we're using as a mold box!

We've 3D printed and made silicone test casts of the insertable part of the device. Here's a test cast of the insertable with electrodes directly embedded in the cast, a huge improvement over our first few prototypes:

Right now, we're moving into a development phase aimed at answering questions like:

  • How many sensors and electrodes do we need?

  • What's the neural density of the inside wall of the vagina?

  • How much variability is there in sensitivity between different people, and between different parts of the inner anatomy of the same person?

  • What's the best way to modulate the signal in response to pressure on the sensors?

  • What's the maximum perceptual spatial resolution of the inner anatomy?

The first-generation prototype had three sensors and three electrodes, and the insertable part was rigid plastic, which as you can imagine was not terribly comfortable and certainly not workable for long-term use. The prototype we're working on now is an enormous improvement: fifteen sensors and fifteen electrodes, embedded in custom silicone that's far more comfortable.

We're excited with the progress that we've made, and looking forward to what we can learn in 2017.

*high five*

There is a SEVERE LACK of real, actual information about human sexual biology... such as how differentiated ARE vaginas between individuals?! Are nerve bundles usually places in similar areas? Is there a drastic change from person to person when it comes to nerve sensitivity in the vulva and vagina? How well DO we know the patterns of arousal within the vagina, regarding when pressing/squeezing occurs and where... and if they can be interpreted as cross-culturally being biological evidence of certain kinds/levels of arousal??

Inquiring minds want to know what we KNOW vs what we THINK we know!

lol! that is a way I'd have never thought of using the 3D printer ;)

this project is SO EXCITING. i can't wait until y'all are ready to launch the kickstarter and go into production! i am going to tell *everyone!*

+1 on the above comment about how very little we know about women's (and queer!) bodies & sexuality, as well! y'all are doing such a great thing here!

wow, this sounds like a very interesting project and I am certainly curious to see how the answers to the questions you have created turn out! Also, WOW detail, very cool.

Love seeing progress on this!

(Also, as you probably know already... always up for being a lab bunny ;) )

Good update
Thanks for the update. I too was curious. I'm enjoying following the progress.

Good Work Keep it up
Very interesting, I hope it is not just for women. I see a very nice toy for guys and girls.

i really love this idea! is there anyway to make it to where besides the sensory part to where a FTM would be able to use the penis to urinate also?? that would be absolutely amazing!! also i think that you will need multipke sizes for the sensors for the inside of the vagina as we all have diverent sizes and something that small may not work in someone larger

Question about sensor position
Good progress ! Are the electrodes only placed on the sides and back face (facing the back when inserted ) ? Why don't you place electrodes on the front side ? I imagine this kind of dildo would be subject to a lever motion pressing it more against the front side of the wearer's vagina ? I cant wait to see further progress you make on this ! Enzo

Re: Question about sensor position
This was just a test cast to make sure the electrodes would stay put in the silicone. The actual live prototype has four rows of sensors and electrodes (front, back, and both sides). The prototype I'm working on right now has 18 sensors and 22 electrodes--18 sensory stimulation electrodes and four grounds.

I know this might sound strange, but I think this is a great idea! I think it could really be a game changer in the bedroom for those willing to try it!

I hope you update more often. At least once a month.

I also wanted to know how close this Dildo is to a real cock? Do you know what the differences are in the sensations to this and a real penis?

Also, do you know how long this will take before it comes to the market? Will it be another two to four years?

Thanks for posting! I hope to hear more about it in future!

This is great! I'm already obsessed and craving the next update! I hope a kickstarter or something is made!

Re: Nice!
We are planning on doing a Kickstarter once we reach that stage. :)

RE: Re: Nice!
Please make the skin on the penis as soft as possible for the receiver. We also need to make the feeling of being penitrated for the receiver real as possible.

Definitely up for this!!

I've heard tell that Livejournal may be shuttering soon, though, so is there another place you have this on the internet that we can follow? Perhaps tumblr?

You can always keep up with us at tacitpleasures.com :)

Are these connected. Would it not be better to use Bluetooth or some similar tech.
Oct. 18th, 2017 01:47 am (UTC)
This idea is sooooo cool. Wow. Can't wait to see the finished product! I have one idea though. It would be cool if the dildo was not hard right away. You'd have to stroke it first for it to get up. But hey, that's just one of my ideas. Keep up the good work! You guys are doing great! 👏👏👏

I've just stumbled upon this article. Please make this a reality!! PLease make a kickstarter as soon as you can. I've been thinking about creating something like that since i was in high school. O_O PLEASE MAKE IT HAPPEN
