Overview The Need The Device Lessons Learned Market Analysis Kinematics Calculations Next Iteration Market Analysis

The Need 30% of U.S. deaths in 2000 due to lack of physical activity, smoking, and poor diet. 43.4% of elderly deaths caused by heart disease, stroke, and diabetes. 32.9% of elderly without physical exercise for the past month. 19.5% of elderly are obese.

Advantages No stored energy Does not constrain motion Safer than weights or springs. Does not constrain motion Same degrees of freedom as the body Matches the force of the user Viscous damping acts as a passive feedback system Dual-direction resistance Exercises complementary muscle groups.

Calculations Maximum Torque: ~40 Nm Average Joint Rotational Speed: ~1 rad/s Linear Damper (10cm moment arm): Maximum Force: 400 N Damping Coefficient: 40 N•s/m Rotary Damper (1:1 gear ratio): Maximum Torque: 40 N•m Damping Coefficient: 40 N•m•s/rad

Preliminary Testing Sketch Model

The Next Iteration Damper Selection Proper Ergonomics Rotary damping for elbow joints Oil-based dampers Proper Ergonomics Mirror human joints Dual support handle to eliminate torque on wrist Contact: Kristina Martin Director of Aquatic & Fitness Programs Zesiger Sports and Fitness Center

Market 35+ million elderly in U.S. Increased physical activity could save $77+ billion in medical expenses. 95% of elderly health care spending on chronic diseases (i.e. diabetes, heart disease and stroke, cancer and arthritis).
