Thank you!

No I actually didn't have muscle fibers in mind -- there's quite a bit of ongoing research specifically in that area.

Yes! The catch is any notch you make will weaken the material significantly and you'll have fatigue failures. That's the sneaky part of using a flexible sleeve, you don't introduce…

Thanks!

I did experiment with various ways of allowing light to escape but nothing came close to the properties of a total air gap. You can actually measure (relative) bend angle with it l…

I didn't include this in my article but I did some experiments early on (for a different idea) with air bubbles in oil inside a Teflon coated tube but that presented a lot of chall…

I used it more for future-proofing in case I wanted to do sensor fusion or something like that later on -- currently it's just 1D filtering so I could have used anything. Also I'm …

Since the sleeve is a stretchy rubber as long as the inner diameter of it is a bit smaller than the outer diameter of the fiber it holds just fine. For more dynamic applications, t…

There are a lot of cool applications indeed! I was able to use it to do gait for a soft robot "leg", but I have to wait for the paper to be published later this year before going i…

There are a lot of similarities in the approach to the linked paper (which is a very cool concept) and I saw a lot of similar concepts in my lit review. At a high level, my sensor …

Great ideas! Even though I haven't implemented it fully it is possible to sense multiple bends because each bend will always have the same relative attenuation (across the strands)…

I explored FBG sensors early on and they are very cool -- I was aiming for a less expensive and more robotics-oriented application. Something that can be seamlessly integrated into…

Fixed -- thanks! And yes exactly! I had access to basically any piece of equipment I could want (including a cleanroom that can create ICs) but then basically no one would be able …

Thanks!

The short answer? Weekly meetings with my advisor! Long answer: I also had 2 years of classes but I started working on my research immediately, while taking classes. By the time I …

I was aiming for significant attenuation when bending, so scratching wouldn't be enough.

Thank you!

3D printing does affect the light passing through significantly. There are a number of options for fabricating these but most of the successful ones involve cutting (can even use a…

The finger bending example is certainly a classic for something like this but I think it truly shines in soft robot examples like flapping wing robots or swimming finned robot, whe…

Haha this made me laugh -- thanks!

Oh yeah cable companies have long been able to do that - I wasn't trying to compete with or replace that technology. My work was soft robotics-focused with simplicity in mind.

Indeed! How do you know her?

Yeah initially doing literature review was a bit daunting because of all this existing work, especially FBG-type sensors, but this idea is so fundamentally simple that its been mos…

Thanks -- I definitely relied heavily on my wife in order to maintain that pace.

Thanks!
