Краткое описание проекта

The present proposals under the project concern to a category of applied researches and are directed on development of acoustic methods of media parameters measurement and use of the advanced methods for research of properties of new materials, composite structures, ceramics with the purpose of creation on their basis of bulk and surface acoustic waves sensors for application in environment protection. As a result of the project implementation creation of laboratory prototypes of sensors highly sensitive to a raw of toxic agents in gaseous, liquid and in disperse-sprayed states is expected. These acoustoelectronics sensors are supposed to be miniature, fabricated of nonconventional but nevertheless accessible materials, with minimal mass and production cost. Such direction of researches reflects contemporary dynamics of development of the given field of activity [1-8].

Scientists and engineers of the IRE RAS - the leading institute of the project, have powerful contribution to becoming acoustoelectronics as a separate field of a science and engineering. In IRE RAS namely the idea on surface acoustic wave (SAW) use for signal real time processing application was stated for the first time, a row of basic designs of SAW devices was suggested, a number of new material with small acoustic absorption in microwave range was suggested and elaborated, that permitted in turn to suggest designs of resonators and sensors working in microwave range. Scientists and engineers of the IRE RAS have long time experience in elaboration designing and transfer to mass production of acoustoelectronic devices both for military and civil applications [9-18].

For the solution of the problems indicated in the project it is supposed to carry out works in the following scientific and technical directions, preliminary results on which are already obtained by participants of the project. These directions are:

1. Revealing of connection between acoustic wave absorption and dielectric losses in a number of dielectric materials and solid solutions on their base. The systematical research of that problem is very important since it allows us to search new materials for high quality acoustic and microwave resonators, wave guides, acoustic delay lines etc.

2. Investigations of micro- and nanoceramic materials by acoustic methods for the purpose of developing the model of ceramic grain boundary. Studying of influence manufacturing process on properties of grain boundaries when the grain size down to nanometer for the purpose of controlling practically important ceramics characteristics such as low acoustic losses, high thermal conductivity, isotropy.

3. Investigation of the phenomena connected with dispersive acoustic modes transformations to bulk acoustic modes in layered structures film-substrate and in plates with big thickness to wavelength ratio. These investigation are important for SAW devices with stable frequency characteristics.

4. Investigation of the preliminary observed recordly high responses of physical values sensors based on bulk acoustic wave (BAW) resonators with quarter-of-wavelength sensitive covering and thing film piezoelectric BAW resonators with substrate acoustical isolation. Use of such resonators will permit to create sensors of physical values (humidity, temperature, gas presents) possessing extremely small size (smaller than similar SAW counterparts) and compatible with small size microwave antennas that will permit to use such sensors in wireless long distance monitoring systems.

5. Investigations of temperature dependencies of acoustic characteristics of thin dielectric and metal films by the method of composite acoustic resonator and elaboration of fabrication technology of such films. It is very important for creation of thin film resonators and layered resonator structures of stacking type.

6. Investigations of previously discovered during the works of ISTC Project #1030 anomalous influence of temperature and sorption of molecules of external gas media upon the propagation of surface acoustic waves (SAW) in ferroelectrics irradiated by E-beam. This phenomenon is supposed to be use at elaboration of SAW gas sensors with new operation mechanism, in particular of SAW humidity sensor with threshold sensitivity by several order of magnitude less than in all other known SAW humidity sensors.

7. Elaboration of new nondestructive methods for control of thermal phenomena in solids and in liquids based on acoustic wave propagation in uniform rods and thin plates for the purposes of phase transients investigations, investigations of bacteria growth and studying of micro droplets of volatile compounds.

Thus main principles of new acoustic sensors creation on the base of new materials, and use of surface and bulk acoustic wave in the frequency range up to 5 GHz will be developed as the result of this project implementation.

Interaction with the foreign collaborator will be held as discussions of quarterly scientific reports and intermediate results, exchanges of experimental samples, joint elaboration of some theoretical statements of the Projects with successive organizing of joint symposiums and seminars, joint publications in leading scientific journals.

The project as a whole answers overall objectives of the ISTC. It provides an opportunity to group of leading scientists and engineers of IRE RAS having knowledge and qualification in the field of creation of arms to be reoriented to the peace activity directed on perfection of the existing chemical and biological control of the environment which is especially actual in connection with last events in the world.
