good night, this stuf is now used in the "new high tech" stuff for vr however now you pay nearly 2000 for 5 flex sensors, 1 gyroscope, and a esp 8266 board. well and now some "high tech companies" finally learned that emg's exist and made something so revolutionary new and unimaginable that it is exactly one of my high school side projects but on a smaller scale and with ai stabilizing. however since bend sensors are a lot cheaper I am looking to building them first for the full body tracking for things like animation, exoskeletons, neurobooster, etc. all things I still need to make working right, since emg's where just to expensing, and in some cases would crash because I could not insulate them against high voltages.
My guess it that device changes resistance based on bend radius, which affects how much surface of the velostat makes contact with each other. The more surface is making contact, the lower the resistance. The tape seems to be black fabric tape (gaffers tape or something similar), and it shouldn't be conductive. The black stuff, on the other hand, is the velostat, and that is actually made to be conductive. It's been quite a number of years since this video was posted. I hope you're doing awesome things now!
What range of resistances were you getting? I have been looking at making thee in class. I tried conductive paint on a t-shirt and it worked great but it did not last very long.
ok, I'm wanting to make a pressure switch for a flash light. could you make a video on how to do that? I am going to attach the switch to a bow handle for ease of access. or if you have a video on a switch you have already made can you provide a linK. Thanks
Cool sensor. I have a Hobbyist question. I was wondering how much you would of measured without the tape and wire, just by moving the test leads closer together
@Plusea is possible to measure the extension/fexibility such as an extensimeter? better written, is possible to count the cycle of up/down of the band by this project you made? I mean that i need to know if is possible to measure by this project, the breath rate.
Nice, it's a bendable variable capacitor :-) I didn't think of using it as a bending sensor, but it seems usable as a capacitive toucch sensor as well.
Your never too old to stop learning. I want to know what this is too. I started in the knitting and wound up here. I still would like to know. What is this and what is it for? Thank you
Flex sensors are similar to switches, except they provide proportional feedback depending on how far they're triggered. In this case, imagine tying that strip to your finger. If you were to then extend your finger, it would give one reading; bend your finger and get a different reading; bend it a little bit and get a reading in between the two. Flex sensors have lots of uses, but the most fun (in my opinion) would be for gloves that can read the positions of your fingers to interface with a computer or microcontroller. Flex sensors can be purchased (roughly 8 bucks for a small one), but the costs can add up if you're using several. Velostat is a very inexpensive (e.g. 4 dollars for a square foot on adafruit.com) sheet of conductive material that offers less electrical resistance when compressed, so it seems like this would make an excellent alternative for hobbyists.
You're* also, never too old to stop learning? Does that mean we should all just stop learning and give up. Because if you were too old to stop learning then older people couldn't stop learning. I think you meant you are never to old to learn.
Hi do you need the fabric? it looks like you need just some wire, duct tape and velostat? i tried but mine does not work.. seems easy though.. maybe it's the velostat side i use? Basically it's just three layers of velostat two wires and duct tape right?
I can mistake,but it seems to be not like that. Inbetween wires need to be conductive material,like graphete there ruclips.net/video/1oF6iY-OO4Q/видео.html
Looks like this reacts more to pressure than bend. Else I see this as a cheap way of making glove sensors and even may be if taken further cheap sign language readers.
Correct me if I'm wrong, but it looks like you're using duct tape and electric tape... but not fabric. Or wait, is the fabric conductive as well? Is that what's on the edge there? That makes much more sense now. -- That's a really cool pin header with alligator clips you've got there, where did you get it? -- Finally, are you measuring a change in resistance, or capacitance? -- Please explain! :D p.s.: Good Night! ;-) Real hackers/makers stay up late. This is pimp.
@sweetbabynoa ... and her mom wishing her a good night. ;) Great video, I'll try to produce one like that for an interactive lamp project we're doing in class. Thank you!

the song in the background is of David Matthews and the song is Crush... :P
best part is when processing doesnt work at first
Get here looking sensors and stay for the music... dave matthews band ftw!

Perhaps You know which fabric one is better to use with velostat and bend it? Cooper tape, faraday tape, conductive nylon? I haven't found comparisons

^grammar nazi lol :P
hi thanks for sharing, do you any suggestion to use instead of velostat, because in my country I can not find velostat
google stickytape bend sensor and it should get you to all the info:-)
sorry but i can't seem to post links here.
which software are you using for checking the variation? please reply soon..
nice, you coud strap two FSR to two fingers and control mouseX, and MouseY.
Awesome! How does it work?
what is the range of resistances values??
are u still here Plusea!?.. question. Whats that orange thing?? Does this bend sensor work just as the ~$13 flax sensors?
wonderful :)
i was looking for a this
How to record the data of the cycles.

Really good.

is it copper wire????
I like your video, exactly bcz it's silent (if we dont take into consideration the music in the background :))
All in all, it's a good work!
what is it and whats it do :o
Thank you very much
whats that black thing?
what is this?
could u please tell me what the yellow one you stick to both end sides of tape?
That's a thin copper sheet or we can call it as copper tape
awesome

0:36 Is this set by a thread
If you need to ask, this video isn't for you!
Good Night! :D :)
@sweetbabynoa ... and her mom wishing her a good night. ;)
Great video, I'll try to produce one like that for an interactive lamp project we're doing in class. Thank you!
wow really great .................
awesome!
good night!!
That's what I was going to say!
And you are just now commenting it's over a year old
Wait.......why am I even watching this?
+The Fallen Angel same here
wtf is a bend sensor?
thank you so much / çok teşekkür ederim :)
takeorder-esf
wtf with the background song!?
lol TAKE MY LIKE
XD!
