By using an easy and effective method of depositing conjugated polymers (PEDOT:PSS) on flexible substrates, a new design for organic bioelectronic devices has been developed. The purpose was to build up a system that mimics the motion of neurotransmitters in the synaptic cleft by obtaining an electrical to chemical signal transport. Fourier transform infrared (FTIR) spectroscopy and Raman measu...

The first step of medical treatment is the diagnosis. This investigation is focused on some fundamental mathematical and physical characteristics of such diagnostic tool, namely the Electrical Impedance Tomography (EIT), a subject of great scientific and public interest (Holder, 2005; Brown, 2003; Lionheart, 2004). The basic EIT’s assumption is that different biological tissues can be distingui...

This experimental investigation was carried out in order to determine the electrical characteristics of several hydrocarbons of low dielectric constant. All measurements of the conduc ivity were below 1 picomho/m (u.10A/V-m 10-14 ohm'lcml). This category ncludes most petroleum products, petroleum distillates made conductive by adding anti-static additives, and liquified gases. Of particular int...
