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 t ensoresistors for medical applications.
