Application to Detection of Infections• Noscomial infections (fungal or bacterial) lead to almost 100,000 deaths per year• An important goal is the detection of the root cause of infections caused by handshakes, touching of equipment and/or object in buildings
Technological Motivation[*] Katsuyuki Fujii, Masaharu Takahashi, and Koichi Ito, “Electric Field Distributions of Wearable Devices Using theHuman Body as a Transmission Channel”, IEEE Trans. Ant. Prop. Vol 55, No. 7, Jul 2007.
Proposed Concept On skin modified “coaxial” channel on the arm model skinRegular fatcoaxial cable muscle Ground layer Feed wire where signal is “outer conductor” launched into the transmission line Signal layer “innerEquivalent circuit representation conductor”of a coaxial transmission line
Electric Field Distributions 8 mm distance => field drops -30dB to -50dB
