Cabe, can you rephrase the question? What depth are you asking about?

After watching the video again, it looks like the "swellable" needles may hurt.

What is the depth they take?

I agree, and very good point. Not just EEG, but other types of diagnostics as well.

In all seriousness, EEG connections could benefit from piercing the skin.

I've read some of the same cyberpunk sci-fi, Cabe. The nervous system interface would be both wild and appropriate technology for this application.

Reminds me of Cyberpunk type "wetware" medical tech. Next step, interfacing the bandage with the user's nervous system.

Chuck, I know it seems counterintuitive, but the tiny plastic hooks are so small and flexible/soft that they're supposed to be painless. The whole point of the device is adhering to wounds while not causing pain and then being easy to take off when not engorged with fluid.

Cabe, good analogy of a plunger with Velcro. it's only hard to pull off while the hooks are engorged with fluid. And I agree--it's gross! But that's part of the fun.

This product shows once again that we can learn from nature. The challenge is knowing enough to understand where to look.

Using germs to kill germs? Sounds pretty ironic. I doubt many people would be willing to use this.

At this year's MD&M West show, lots of material suppliers are talking about new formulations for wearables and things that stick to the skin, whether it's adhesives, wound dressings, skin patches and other drug delivery devices, or medical electronics.
Researchers at Lawrence Livermore National Laboratory have published two physics-based models for the selective laser melting (SLM) metals additive manufacturing process, so engineers can understand how it works at the powder and scales, and develop better parts with less trial and error.
Materials and assembly methods on exhibit at next week's MD&M West and other co-located shows will include some materials you should see, as well as several new and improved processes. Here's a sampling of what you can expect.
More plastics are coming into hospital equipment, as well as single-use, patient-friendly medical devices and wearables.
The Food & Drug Administration has approved a 3D-printed, titanium, cranial/craniofacial patient-specific plate implant for use in the US. The implant is 3D printed using Arcam's electron beam melting (EBM) process.
