This question surprises me. Bend location == locate where something is bent. Then some video's of the researcher bending a tube. Is there any confusion possible?
OP updated his blog post after I posted my comment. The opening paragraphs are now very clear and awesome.
Thanks for sharing your work. Would you be able to compare your device to the fiber optic one used in the data glove (e.g., https://iopscience.iop.org/article/10.1088/1742-6596/2464/1/... ).
Our lab has done a good bit of work around elastomers similar to the linked paper, such as multitouch pressure sensing (https://ieeexplore.ieee.org/abstract/document/9674750). The authors of your linked paper can actually achieve what they've done with a single light source by using one of these! The zones are key (https://www.st.com/en/imaging-and-photonics-solutions/time-o...)
Very beautiful research and thorough documentation. I initially wanted to comment that this looks a lot like time-domain reflectometry on a conceptual level - but as Cindy Harnett seems to be your advisor, you probably know that already :)
Indeed! How do you know her?
This is fantastic! One can easily imagine some minor refinements that would allow this to be mass producible with very high accuracy. And the applications are abundant. I imagine you could use space filling curves to make 2D or 3D sensors that could cost-efficiently give robots a sense of touch. Wrapped around something like a flexible tube you could make it directionally sensitive for proprioception. It's easily pos…
This is cool as hell! I hope your PhD continues well, and that this invention serves you in the future. Do you put any lube on the interface between the silicone sleeve and optical cable? I imagine the bending action will cause displacement, and friction there could rub and/or cause the nominal position to shift around.
That's super cool and I hope you don't mind a little bit of unsolicited feedback but the first question everyone's asking is "what does it do?" At present the blog post starts out with two paragraphs talking about the format of the blog post and the applications but not what the sensor actually measures.
Good point -- I need to better explain what "bend localization" means on a more practical level pretty early on.
