Overview Review of design motivation and ideas Our prototype:

(Current) Features (Future) Versions

What sets us apart from the competition (ideally) Testing/ proof of principle

Tremors induce appropriate muscle response▪ Oscilloscope readings▪ Literature findings

Sensors detect abnormal arm movement▪ LEDs

Next steps

Problem & Clinical Motivation Target: 5.5 Million Americans

Problem: Intention Tremors in the arm

Clinical Motivation: Solution to perform daily tasks Eating Drinking Writing

Objective Statement

Mission: Produce a non-invasive motion dampening device that efficiently attenuates tremor and provides comfort, stability, and peace of mind
