Stabilization of organic materials for sensors

This paper deals with research and development of organic humidity sensors. These sensors are based on organic sensitive layer which is applied on the substrate with interdigital electrodes. The main work is focused on the stabilization of organic sensor layers. The stabilisation of mechanical and electrical parameters is based on passive polymer matrix where the active organic sensitive material is fixed. The sensor sensitivity, impedance-humidity characteristics and long term stability of electrical parameters were measured and discussed in detail.
