Pristupačnost- Measurement of active piezoceramic elements, namely, their dielectric, electromechanical and piezoelectric properties. These elements will be used in measurement setup and contact and non-contact HIFU transducers modelling and construction in extremely nonlinear operating conditions, using high amplitude multiharmonic continuous signals (up to 100 VRMS).
- Determination of equivalent circuits for active piezoceramic elements in the vicinity of all significant resonant modes by fitting available models for nonlinear elements behaviour with measured electrical impedance data.
- Implementing a novel measurement procedure which is to include tracking of the resonance frequency of the active piezoceramic elements, dependent on the level of the excitation signal.
- Virtual prototyping of new contact low-frequency focused ultrasonic systems and new high-frequency ultrasonic systems with flat and curved radiation surface.
- Testing the samples of biomedical material (hard and soft tissue samples) using the proposed novel measurement system and new procedures.
