Personal Fall Detection Device
The Personal Fall Detection Device (PFDD) project, developed by students at the Georgia Institute of Technology, addresses the critical issue of accidental deaths due to falls among the elderly. This automation-driven system consists of interconnecting devices designed to detect falls and provide immediate assistance without requiring the user to press a button. The lightweight transmitter can be worn around the neck or ankle, and the system automatically contacts emergency services, ensuring safety for individuals aged 75 and older living alone. Estimated development costs are $150, with no monthly fees for users.

Project Overview Falls are responsible for 70% of accidental death in persons aged 75+ • PFDD is automated system of interconnecting devices to detect user falls • Primary client elderly people living alone. May need help if they fall • Current devices on market require user to press a button to gain help • Estimated development cost $150 • No monthly fee. Presented By: Matthew
Design Goals • Transmitter Package • Fits around neck or ankle • Weight: under one pound • Covers average-size house • Battery life of six months • Receiver Package • Automatically calls emergency service • Prevents “false falls” • Low maintenance Presented By: Matthew
