Piezoelectric micromechanical systems (piezoMEMS) are often subjected to harsh mechanical and electrical loads during operation. This study evaluates the effects of history a lead zirconate titanate (PZT) layer on electro-mechanical response structural limits multilayer stacks. Electro-mechanical characterization was performed under biaxial bending employing Ball-on-three Balls (B3B) test virgi...
Electrical cardiometry and detection of left ventricular failure in right ventricular heart diseases
The aim of this study was to provide an increased level of evidence on surgical management of high-tension electrical injuries compared with thermal burns using a case-controlled study design. Sixty-eight patients (64 males, 4 females, aged 33.7 +/- 13 years) with high-tension electrical burns were matched for age, gender, and burnt extent with a cohort of patients sustaining thermal burns. Dat...
HYPOTHESIS This study investigated whether pressure changes common to scuba diving and to hyperbaric oxygen therapy would not cause crush damage or leakage from critical seals in commercially available cochlear implants. BACKGROUND The implanted packages of cochlear implants are susceptible to electrical failure caused by leakage from critical seals and to crush injury when exposed to changin...
