Ultrasonic Micro Motors, It’s all in the Shape
A while back, I wrote about permanent magnet generators and how they generate electricity upon being set in motion. When browsing the papers from our conference in Bangalore, one on the topic of ultrasonic micro motors caught my eye. These motors are electromechanical in nature and instead initiate motion with the application of an electric voltage. Furthermore, these motors are miniaturized to fit a micro-scale environment.
Simulation-Based Design of New Implantable Hearing Aids
Growing older is an inevitable part of life, and with it, our body slowly begins to show that. I recently started wearing eye glasses because my eyesight is weakening. It’s a little unnerving, but I am comforted by the ever-improving technology being produced. My hearing is still fully intact, but the same cannot be said for 17% (36 million) of American adults who report some degree of hearing loss. In most cases, regular hearing aids are sufficient in treating hearing […]
Improving Ultrasound Imaging Systems by Directing Sound Waves
In an earlier blog post, I commented on how acoustic waves are being used in a biomedical setting, to identify malaria in small fluid samples. A more traditional use of piezoelectric devices was written about in the latest COMSOL News. Here, an Italian company, Esaote S.p.A., uses them to produce improved ultrasound imaging systems.
