Thank you to the ROEU Program, College of Engineering, the Biomedical Engineering Department, and Dr. Avanaki for their continued support

Opportunity & Significance

§ 1/3 of American population is obese or near obese

§ $150 billion spent in weight management

§ Current devices are expensive and niche products designed for health enthusiasts

Results

Related Work § Nothing like this at WSU§ Similar belt concept by Welt

but over $200

Change in Waist Circumference vs. Change in Force

Force 1 Force 2 Force 3 F1 Trendline F2 Trendline F3 Trendline

Force 1: R² = 0.8203y = -0.0003x3 + 0.0112x2 - 0.0402x + 0.8539Force 2: R² = 0.8257y = 0.0001x3 - 0.0052x2 + 0.0833x + 0.2716Force 3: R² = 0.9196 y = 6E-05x3 - 0.0031x2 + 0.1834x -0.2719
