It’s a Small World – Designing Piezoelectric Acoustic Transducers as Devices Miniaturize, Part 1

Medical Devices, Multiphysics Modeling, Piezoelectric Materials, Simulation / By

The increasing miniaturization and sophistication of electronic products–ranging from consumer media devices, to medical diagnostic tools, to defense-related sonar applications–presents a bounty of utility and ease for consumers, and an ongoing challenge for design engineers. These seemingly disparate products (audio/mobile device speakers, certain non-invasive medical devices and sonar arrays) share in common a reliance on …

Computational Model for Bolometer Design

Multiphysics Modeling / By

Computational Model for Bolometer Design   Bolometers are used in a number of applications including night vision cameras, astronomy, and particle physics to measure the power of incident electromagnetic radiation. The principle of operation is shown in Figure 1: when a strip of conducting material is exposed to incident electromagnetic radiation, energy is absorbed and …
