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
Target: 5.5 Million Americans Problem: Intention Tremors in the arm Clinical Motivation: Solution to perform daily tasks Eating Drinking Writing
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
Currently available alternatives include: Task-Specific Devices ▪ Neater-Eater ▪ Thomas Steady Arm Drug Therapies Surgical Procedures Drawbacks / Shortcomings: Expensive Cumbersome Aesthetically Unappealing
Distinguishing Features: Feedback Inconspicuous Lightweight Affordable
Qualitative comparisons Quantitative comparisons: Accelerometer voltage output Assess comfort through surveys
Relatively unhindered by regulatory committees No FDA Approval No Pre-Market Approval (PMA) IRB approval
Arduino Rotary Damper Accelerometers Actuator Magnetic Encoder Pressure Sensor
