A finite-element-based formulation for sensitivity studies of piezoelectric systems
Brunel developed new computer models that led to improved design rules, which in turn allowed Redux/HiWave/NXT (the company has adopted new business names since project end) to produce better piezoelectric actuators used for audio devices incorporated into products of Microsoft, Toshiba, HTC, Nissha printing, Yota and Hybra Corp. Over 280,000 units have been sold to date with another 24 million plus units expected to ship from 2014. James East, Engineering Manager at Redux Labs, can verify these facts. This paper describes a finite-element-based sensitivity method developed to identify the key parameters affecting device performance.
