FallSafe: Market

250K hip fractures among elderly in 2010

95% of hip fractures are fall- related 1 in 5 patients die within

ne year of injury

FallSafe: Product Goals

2.009 Fall 2013

Inertial Sensor Detects Fall Deployment system inflates airbag prior to impact Communication system calls for help

Core Functionality Other Requirements Possible Implementations

Easy to remove from fallen user
Low visibility before deployment
Permits discrete use
Detector & Inflator module with

disposable airbag belt

Replaceable gas canisters/charges

FallSafe: Sketch Model: Results

Detection Impact

127 ms

127 ms available deployment time
Comparison: Auto airbag inflates 80 L in 30 ms
Detection/inflation in the course of a fall is feasible

Results Interpretation:
