Me and my girlfriend were forced into a long distance relationship.Her "love language" is touch.I want her to feel my touch despite the distance.So far the only devices I have found were are bracelets that send vibrations like the "bond touch". But it's literally just one fucking vibration.The closest to what I want to do is this :https://www.eurekalert.org/news-releases/980541https://www.science.org/doi/10.1126/sciadv.ade2450But it's not public and I'll have to remake it myself. I doubt I will be able to do most of these DIY. For example the actuators :>A flexible actuator consists of a multilayer flexible coil, a soft support, a PDMS film, and a magnet. The soft square-shaped support was fabricated from a cured PDMS (prepolymer and cross-link agent = 30:1) with a thickness of 2.2 mm. The PDMS films with different thicknesses were spin-coated from 5:1 PDMS at 200, 300, 400, and 500 rpm for 30 s. With laser cutting, these soft structures were all machined into designed shapes. A square neodymium 50 magnet (M0350, SuperMagnetMan) with dimension of 3 mm by 3 mm by 0.5 mm was fixed to the flexible film relying on the bonding and curing of PDMS. After assembling the coil, the support, and the film in alignment, a flexible bendable actuator was obtained.But even this seems lackluster. It looks like the actuators will just act as individual buttons pressing onto the skinCan you guys give me some pointers? Or alternative DIY projects to imitate touch long distance? Just need some directions to start researching and learning on my own. My experience with electronics is pretty poor, just an arduino when I was 16.Thanks
>>2863311I'm sorry dude, but she's getting " touched" by someone else right now. Just let her go and find a new gf.
>>2863442No she is not.She is autistic and very socially awkward. That's also why touch brings her comfort.She spends almost all day at home and don't talk to many people.I have her on video call almost 24/7
>>2863311there are comercially available and pretty cheap haptic vests etc for VR, but yeah, it's just vibration
>>2863451Lmao, like that other guy said. She will get fucked by someone else. You have to move back close to her. If you can't cheat early and get in before her. You will regret it if you don't. You will dismiss this advice however it's the best advice you will ever get on the subject. You should remember I said this when it all goes to shit for you and you didn't listen.
>>2863311You want something impossible. If it existed, and was at all affordable, someone would have been selling them by now. You are talking about remote sex basically, which is like some cyberpunk holy grail. I’ll save you so much time here. You cant have it, and if it exists, it’s going to be a sex toy already.
yea move moron. e-fucking retard over here.
>>2863451bro does she have a sister?
>>2863612bro who hurt you?
>>2863311Don't listen to these retards, she's not doing anything - it's just as hard on her as it is on you, It could be worse, at least you're not international (I assume).
>>2863311>Me and my girlfriend were forced into a long distance relationshipYou have to be 18 to post here Romeo.
>>2863311Don’t listen to the retards. As the image shows you’ll need some kind of ‘pixels’. The shit from the paper probably works well but you’re probably not going to be diy spin coating it into a working product. Last time I checked - which was around 2018 - shit like this was done experimentally with shape memory alloys (Nitinol) and something that provides heat to it and is actuated remotely (ie some receiver and a nichrome wire). You bend the nitinol wire and when heated it bends itself back to its original (or ‘learned’) shape. They are pretty slow though, mostly limited by how fast you can heat them without causing a fire. But using the right layout something like a slowly bending finger can be simulated quite well
>>2863442Thanks, I felt a little awkward, pointing that out...
>>2864725>>2863451Literally me 15 years ago>>2863442>>2863612Me 10 years ago>>2863462>it's just vibrationMe now
>>2866727good post
>>2863311Just tell her boil some water and pour it on her face and imagine that you're peeing on her.

>long distance relationshipNo Such Thing. You are not your mind, you are your body, relationships are reciprocal, organic symbiotic systems. "Long distance relationship" is an oxymoron.
>>2863311Time to go buy Lovense products
Build a hugbox with a network enabled remote control.
>>2863311Nobody is forced into an LTR, even criminals have a choice to not do the crimeMove to be by her or be ready for the relationship to not make it
OP, I have a business proposition. We simply engage in a phone call for you to direct me, and I'll enact all the touch you desire on your girlfriend.>>2863671Let the man dream. OP, my penis is your penis.>>2868150You're not even a person. Shutup, hylic.
>>2863311What kind of touch are you trying to emulate specifically? If you want her to be able to feel you hug her, feel your arms across her body, that might be a little unrealistic right now. If you wanted to simulate just placing a hand over her shoulder, or on her head, or something simple like that, it might be more realistic. The key here is to limit your expectations. It's not going to feel "real" no matter what, especially with only minimal electronics/programming experience.One idea I had might be able to simulate a very rudimentary hug. I'm thinking basically some straps and a motor that tightens/loosens the straps and have those go around her chest. tighter hug = tighter straps.You also have to consider how you are going to detect the touch in the first place. If you want to digitize and transmit a hug, you have to be hugging something yourself, and ideally it would be at least approximately the same shape as your girlfriend. This actually might be the easiest part however, depending on what tools you have at your disposal. If for example you have a 3D printer and (ideally) a 3D scanner (I've had great results with a creality ferret) you could simply scan her in the desired position, do a little post-processing cleanup, then break up the resulting .stl file into many smaller ones sized to fit the build volume of your printer. Then you just print her out one piece at a time, glue the pieces together, and bob's your uncle, you now have a highly detailed, 1:1 scale model of your girlfriend. You would also want to make one of yourself to give to her as well. (If you have a printer but not a scanner, there is an alternative which I'll describe later.) As remarkably strange as this may seem at first glance, even just having a model of your significant other to hug or sit next to could be comforting, especially if printed with flexible TPU and/or coated in silicone rubber or something. (think flex-seal)one of several posts with ideas + potential problems)
>>2868425As for ways you could actually simulate the sensation of touch, I think the articles might be on the right track. You could probably simplify it though. My first thought was to use solenoids that push a little piston onto some kind of flexible skin-contacting layer. (silicone would be my first thought) Basically have a bunch of solenoids and each one pushes on one spot acting as a "touch pixel" You could convey more or less pressure by controlling them with PWM or analog output, with higher PWM duty cycle or higher voltage making the solenoid rod extend farther/with more force. (this would have to be calibrated and would probably be tedious) If you want higher "touch resolution" you just have more solenoids/unit area. You would also need to have a way to mount them to the skin-contact layer in a way that they can push against it. Also you would want to make sure that the solenoids won't get too hot. Its possible that with small, relatively low power ones no cooling would be needed, but you might also need to consider attaching small heatsinks to them. Active cooling would be very amusing but probably not practical. Another idea for "touch pixels" would be some kind of small stepper motor with an irregularly shaped thing on the end, like a cam. When you want to have that "pixel" indicate pressure, it rotates so the long end is pressing down against the skin-contact layer. Varying levels of pressure can be achieved by varying how far the cam is rotated.
>>2868426Both of these would become very bulky very fast as you increased the surface area you wanted to cover. If you wanted something across your whole core body and arms for example, you would have a LOT of cables and probably would be drawing a fairly substantial amount of power. You would also probably need to use multiplexers as you run out of pins on your microcontroller, and would also need to be using mosfets or some other power transistor to actually deliver the power needed. On top of the complexity of the wiring, number of components, cooling and power requirements, and general clumsiness of this hypothetical contraption, you would also need to consider the weight. Both motors and solenoids are made of metal, and if you wanted to cover a large portion of a body with a high resolution device, you would need LOTS of solenoids/motors. Finding a way to keep all of them attached to the underlayer, and keeping that attached to a person, would be its own challenge.Another thing that probably isnt practical for DIY but might have potential would be a pneumatic system. I'm imagining many small air bladders embedded into some kind of suit, and to apply pressure to a given part of your body, compressed air is allowed into the corresponding air bladder, then released when the pressure stops. This would solve the issues with having hundreds of hot, heavy solenoids sticking out all over your body like a pincushion, but would require a complex, dense network of tubes and valves to pressurize/release all the bladders.These could be embedded into the suit along with the bladders in theory.
On an unrelated note, I just thought it would be important for people to see this from the first linked article.

>>2863311Outside of a remote controlled vib I don't really see a way of drying this.Like other anons said, LDRs are fucking hard..Honestly this seems like a low tech situation, weighted blanket and phone/vid sex might be the best bet here
