Welcome to INNOXACS !

INNOXACS – Innovations in Crystal Acoustics – Dr. Manfred Weihnacht is a Saxon company, providing to customers from industry and science independent research service on fundamentals, modeling, and application studies of acoustical phenomena in solids and fluids.

Based on a longstanding experience in the fields of acoustoelectronics and materials research, INNOXACS proudly offers to customers broad expertise on different topics in microacoustics.

Fundamentals of crystal acoustics

• Analytical treatment of linear and non-linear behavior of acoustic waves in solids (primarily in piezoelectric crystals) and fluids
• Basics of temperature dependence (in particular low temperature incipient evidence and phase transitions) and of loss mechanisms of acoustoelectric properties

Modeling of acoustic phenomena

• Computation of acoustic wave propagation and vibration parameters for any technically relevant material systems and geometries, especially on surfaces, interfaces, in plates, stratified systems
• Extraction of material parameters from wave propagation and resonance experiments
• Error analysis at parameter extraction, developing of optimum experimental strategies for parameter determination

Application studies for devices

• Simulation of surface acoustic wave (SAW) sensor behavior of different types (detection of temperature, mass loading, properties of fluids) and elaboration of device optimization criteria
• Modeling of SAW based fluidic actuators, development of adapted material systems (crystal orientation, thin film coating, actuator plate geometry)
• Figure-of-merit based specification of material systems use
• Specialized simulation of SAW filter behavior on the base of charge distribution analysis
