Controlling Tremors As They Happen

Some neurological disorders, like Parkinson’s disease, can cause muscle tremors which can get worse as time goes along. In the beginning it may not be too difficult to manage, but as the disease progresses the tremors get worse and worse, until day-to-day movements are extremely difficult. Even picking up a fork or pouring a glass of water becomes nearly impossible. Some helpful tools have been designed to limit the impacts of the tremors, but this new device seeks to dampen the tremors directly.

A research team from Fresno State has been developing the Tremelo, which is a hand stabilizer that straps onto the arm of a person suffering from tremors. It has sets of tuned mass dampers in each of two enclosures, which rapidly shift the weights inside to counter the motion of the wearer’s tremors. The device has already shown success in 36 trial patients and does an incredible job at limiting the amount of tremors the user experiences, and also has a bonus of being non-invasive for the wearer.

The team has successfully trialed the program, but is currently seeking funding on Indiegogo. The project seems worthwhile and is a novel approach to a common problem. In the past, devices (admittedly with a much cheaper price tag) try to solve the problem externally rather than in the direction that the Tremelo has gone, and it’s a unique idea that shows a lot of promise.

Super Thin Display Makes Your Skin Your Screen

Researchers in Japan have created a 3-micrometer display that looks like plastic wrap and can make any part of your skin into an electronic display. The idea isn’t new, but this display is far thinner and more durable than previous devices. It also lasts longer (several days) and has increased brightness.

The display uses polymer LEDs to form a seven-segment digit, so you aren’t going to stream Netflix to the back of your hand anytime soon.  However, the team wants to build more advanced displays that could one day replace smartwatch or smartphone screens.

Jellyfish Inspired LED Skirt For Burning Man

[Lumilectric] is getting ready for Burning Man and made herself this fantastic fiber optic LED skirt.

She’s always been fascinated by fiber optics and the effect they create, so she wanted to try using them in a project, and this was just the ticket. The tricky part was figuring out how best to couple cheap fiber optic strands off eBay with a strip of RGB LEDs.

In the end she figured out a way to make rudimentary fiber optic coupling joints using vinyl tubing. She managed to fit 17 strands of 0.5mm diameter fiber into a 6mm diameter vinyl tube. To improve light transfer when it’s all together, you can gently melt the ends of the fiber optics together to glaze the plastic into a single clear surface — don’t melt the vinyl though!
