An 8th Grader’s Exploration in DIY Neuroprosthetics
Several months ago, a crowdfunded classroom got their hands on several of our neuroprosthetic kits – like The Claw and the Muscle SpikerShield Bundle. This allowed students in Nokomis Regional schools to begin experimenting with hands-on neuroscience experiments! One of the students, 8th grader Kaiden K., was interested in developing a prosthetic, but his project had a twist question: What if we had a third thumb?
The Third Thumb
Kaiden’s project is twofold: First, it is a project on the history of prosthetics. From wooden hands to mechanical prosthetics, and now modern, low-cost DIY prosthetics, there have been a lot of remarkable developments along the way as we strive to create new opportunities for people to bring mobility and ability into their lives.
Using a 3D printer and the tools his teacher had crowdsourced on Donor’s Choose, Kaiden was able to develop a neuroprosthetic which anyone can plug into and control with their brain!
By recording from their muscles, Kaiden is able to put other students at the science fair in control of the prosthetic hand.
The second part of the project is still underway: developing a neuroprosthetic which anyone can wear which augments typical human ability and mobility, by adding the third thumb! To put it fantastically: Kaiden is developing cybernetic human enhancements. Literally, 8th graders are contributing to helping us become cyborgs! Too cool.
In an example of parallel, historic discovery – Kaiden had the idea for an extra thumb and began his RnD… then just like many other great minds, discovered he wasn’t the only one doing this work!
This idea has been explored by prosthetic designer Dani Clode – she gave a TEDx talk which is also a great watch!
See her TEDx talk here to learn more about the Third Thumb project.
We’re excited to see Kaiden further refine and develop his project. Kaiden wants to investigate multiple degrees of freedom, perhaps 2-axis control, and see what he can develop. We’ll be sure to update you as he continues experimenting!
Help us win a Grant to Empower a New Generation of Sports Scientists!
Through our adventures at Backyard Brains over the years, we have come to love electromyography, muscle coordination, and the body in movement. We have already begun some classes where we teach muscle physiology through sport! We recently applied for a grant to devote more resources to this new area for us. We made a quick and dirty video under deadline at a local school, and to move to the next phase of the competition, we need eyeballs and likes. Help us out with your screens and your thumbs if you want to!
This is to further develop our fledgling work into making quantitative sports-science an accessible field of research for K12 students!
We’ve tried three sports so far, all favorites of Backyard Brains: baseball, basketball, and soccer. For baseball, we attached electrodes to the triceps while students threw the ball at greater and greater distances. However, the act of throwing a baseball is so violent and fast that the cables would always fly off, making an unstable interface, to put it mildly.
We next tried basketball, with muscles again on the triceps, but our students were pretty young, around 11-13, and they had a hard time launching the basketball with enough force (and good form) to actually reach the basket. Even on adults like ourselves, we did not notice an obvious difference between 2 point and 3 point throws.
Our last attempt was with soccer. We placed electrodes on the quadriceps, and we had markings on the outside gym floor with masking tape of 5 ft, 10 ft, 15 ft, 20 ft, 25 ft, etc.
With this experiment, it was very obvious that the EMG amplitude of the quadriceps contraction increased with the greater distance that the students had to kick the soccer ball, teaching about motor unit recruitment and electrophysiology in a very entertaining way. Learn more about the experiment and the results here!
We have on experiment up currently which teaches students how to study and model Rates of Muscle Fatigue – this is a great intro lab as it can be modified and applied to many sports labs!
There are numerous examples of sports scientists using EMG activity to study the efficiency of different movements, the relationships between strength and endurance, and the difference between skilled and unskilled athletes! We want students who are passionate about their sport to contribute to this body of knowledge, and we want to provide affordable and accessible tools, along with free introductory resources so they can get started running (literally!) Weightlifting, rock climbing, football, futbol, gymnastics, tennis, baseball, shuffleboard… the possibilities are limitless!
This is just the beginning, and we will continue looking for ways to incorporate sport into our physiology experiments, as it makes teaching at the middle and high school very engaging. We would all rather be outside and move our bodies than sit at a desk, anyway.
We’d encourage you to watch the youtube video we linked above, and if you love this project, please like the video! It will help us to win this funding and help bring the experiments to life.
Earlier this year we received an order for a Human-Human-Interface that had our team glowing with excitement. It was addressed to none other than Bill Nye and one of his producers on Bill Nye Saves the World. In this recent Netflix show, Bill Nye and his science correspondents dig into the world of popular science, investigate the unknown, debunk misconceptions, and spread awareness of issues that the scientific community works to tackle every day.
In the last episode of the third season, Bill Nye and his correspondent, the hilarious and insightful Joanna Hausmann, experiment with some mind control… Bill hooks Joanna up to the Human-Human-Interface and describes the neuroscience behind the experiment before Joanna takes total control of Bill. For Bill Nye, Neuroscience has never been more exciting!
Check it out on Netflix: Season 3, Episode 6 of Bill Nye Saves the World! You and your students will enjoy seeing the clip as much as Joanna enjoyed controlling Bill!
Who will be next? Will it be Neil deGrasse Tyson? Will it be you?
Check it out in the store below and bring the excitement of this hands-on lab to your classroom. Use it as a “phenomena anchor” to get your students hooked on the life sciences, and watch as they start digging in deep to understand how it all works.
