The hybrid layer based on poly-3,4-ethylene-dioxythiophene(PEDOT)-multi-walled carbon nanotubes (CNTs) on the flexible polymer substrate is proposed as sensitive element to creation of humidity sensor. The current-voltage characteristics of the obtained films have been studied. It is shown that increasing of the content of carbon nanotubes in the composite leads to decreasing of the resistance of...
The cholesteric liquid crystals (CLC) is sensitive active medium to detection the biological substances. We proposed to use the CLC to design the enzymes optical sensor. The operation designed optical sensor based on changing the wavelenght at minimum transmittance of active medium under the enzymes influence. The functional and electrical schemes of designed optical sensor are developed.
As the active medium of triglycerides optical biosensor the cholesteric-nematic mixtures (CNM) are proposed to use. The efficiency to detect the triglycerides molecules caused by sensitivity the CNM helical structure to the biological substances. The position of wavelength transmittance minimum of optical radiation in CNM contacted with biological agents is changed. The block diagram of the developed...
Sensor elements based on composite films of poly-3, 4-ethylenedioxythiophene combined with nanocrystals of porous silicon and zinc oxide were created. Increasing of nanocomposite electrical resistance due to adsorption of ammonia and ethanol molecules was registered. To evaluate the sensor properties, adsorption sensitivity of obtained composite films was calculated and their dynamic characteristics...
