The Measurement and Analysis of Ion Flow between the Human Body and Local Ground
ECE 791/792 Oral ProposalProject Team: Seshank Appasani, Chris Chirgwin and Paul RiouxECE Faculty Advisors: Dr. Kent Chamberlin and Dr. Wayne SmithCurrent Date: October 27, 2011Project Completion Date: May 2011
Topics
• Problem Statement• General Overview and Background• Past Research• Design Objectives• Testing Processes• Parts Used• Testing Analysis• Timeline• Estimated Cost• Project Allocation
Problem Statement
• To measure the charge flow between the human body and ground in order to understand the nature of the charge exchange.
• Understand the meaning of “Earthing”.
Background
• Until recently, humans have always been in constant contact with the ground
• Recently, humans are more insulated
• Research has shown that this disconnection from the Earth causes health problems
General Overview
• By connecting one’s body to the Earth, electrons can freely flow into the body from the ground.
• By having electrons freely flow, health conditions that are caused by insulation are alleviated.
Before grounding After grounding
Past Research
• Sleep studies• Cortisol level realignment• Pain level reduction• Research yet to be
accomplished
Design Objectives
• Ground the human body.• Design and build an amplifier that will scale the
current exchange• Generate LabVIEW and Matlab code to record and
analyze data.• Discover what constitutes effective grounding of the
human body.
Testing Processes• Connect subject to ground using an anti-static
wristband and a conductive pad• Scale the current exchange• Record and analyze data• Applied to IRB in order to use human test subjects
Parts Used
• Belkin Anti-Static Wristband • Earthing Universal Bed Pad• Amplifier Circuit• LabVIEW program• Matlab program
Belkin Anti-Static Wristband
• General use• Subject attached to
electric ground through anti-static wrist strap
