• 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
Application to Detection of Infections

Technological Motivation
[*] Katsuyuki Fujii, Masaharu Takahashi, and Koichi Ito, “Electric Field Distributions of Wearable Devices Using the Human Body as a Transmission Channel”, IEEE Trans. Ant. Prop. Vol 55, No. 7, Jul 2007.

Ground layer “outer conductor”
On skin modified “coaxial” channel on the arm model
Feed wire where signal is launched into the transmission line
Regular coaxial cable
Equivalent circuit representation of a coaxial transmission line
musclefat
skin
Proposed Concept
Signal layer “inner conductor”
