2.  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

3.  Target: 5.5 Million Americans  Problem: Intention Tremors in the arm  Clinical Motivation: Solution to perform daily tasks  Eating  Drinking  Writing

4.  Mission: Produce a non-invasive motion dampening device that efficiently attenuates tremor and provides comfort, stability, and peace of mind  Device will not inhibit range of motion  Adaptable “Smart” Solution

5.  Currently available alternatives include:  Task-Specific Devices ▪ Neater-Eater ▪ Thomas Steady Arm  Drug Therapies  Surgical Procedures  Drawbacks / Shortcomings:  Expensive  Cumbersome  Aesthetically Unappealing

6.  Distinguishing Features:  Feedback  Inconspicuous  Lightweight  Affordable

9.  Qualitative comparisons  Quantitative comparisons:  Accelerometer voltage output  Assess comfort through surveys

10.  Relatively unhindered by regulatory committees  No FDA Approval  No Pre-Market Approval (PMA)  IRB approval

11. Arduino Rotary Damper Accelerometers Actuator Magnetic Encoder Pressure Sensor

12.  Online Retail  30 Day Money Back Guarantee  Warranty/Servicing  Retail Price: $1000

13.  Innovative concept  Improve customer quality of life  Versatile design with widespread application
