Layers with the tensoresistive properties and their possible applications in medicine Carbonnanotubes Carboxymethylcellulose Nanocompositelayer Tensoresistor	01.01.2018	Ichkitidze L. Gerasimenko A. Podgaetsky V. Selishchev S.	Materials Physics and Mechanics		2	Ссылка © 2018, Peter the Great St. Petersburg Polytechnic University. Layers of different materials, including nanocomposites, containing carbon nanotubes, with the tensoresistive properties are discussed. The investigated layers are divided into two groups: without (group I) and with carbon nanotubes (group II). A group-I material that is the most suitable for fabrication of a tensoresistor is the elastomer with microchannel, filled with a conductive liquid. In group II, these are the (0.2-10)-μm-thick layers consisting of the carboxymethylcellulose matrix, filled with multiwalled carbon nanotubes (∼5 wt.%). The investigated layers can be used as alternative tensoresistors for medical applications. Читать тезис
Electrical conductivity of the nanocomposite layers for use in biomedical systems Acrylicpaint Carbonnanotubes Electricalconductivity Nanocompositelayers	01.01.2018	Ichkitidze L. Gerasimenko A. Podgaetsky V. Selishchev S. Dudin A. Pavlov A.	Materials Physics and Mechanics		4	Ссылка © 2018, Peter the Great St. Petersburg Polytechnic University. Nanocomposite layers consisting of an acrylic paint and single-walled carbon nanotubes (∼1.5 wt.%) have been investigated. The investigated samples had a disk shape with a diameter of 20-30 mm and a thickness of 2-50 μm. After exposure in water for 350 h, the layer mass remained almost invariable (a mass loss of ≤ 1.5%) and the layer samples exhibited high adhesion to glass substrates and a conductivity of ∼ 40 S/m. The layers consisting of the nanotubes and acrylic paint exfoliated from the substrates for ∼1 h. After heat treatment at a temperature of 140 °C, all the layers exhibited a semiconductor-type temperature dependence of the resistance. The prospects of using these layers in various medical products, e.g. implants for wireless energy transmission, have been discussed. Читать тезис
