  2. 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

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

  4. Objective Statement • 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. The Competition • Currently available alternatives include: • Task-Specific Devices • Neater-Eater • Thomas Steady Arm • Drug Therapies • Surgical Procedures • Drawbacks / Shortcomings: • Expensive • Cumbersome • Aesthetically Unappealing

  6. Our Design • Distinguishing Features: • Feedback • Inconspicuous • Lightweight • Affordable

  7. Stead-Ease Concept Showcase: I

  8. Stead-Ease Concept Showcase: II

  9. Technical Feasibility • Qualitative comparisons • Quantitative comparisons: • Accelerometer voltage output • Assess comfort through surveys

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

  11. Manufacturing Costs Arduino Rotary Damper Accelerometers Actuator Magnetic Encoder Pressure Sensor

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

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