LEAD-FREE BNKT PIEZOELECTRIC ACTUATOR
An actuator is a device that converts input energy into mechanical energy. According to various types of input energy, various actuators have been advanced. Displacement in the electromagnetic, hydraulic and pneumatic actuators achieve by moving a piston via electromagnetic force or pressure, however the piezoelectric actuator (piezoceramic plates) displace directly. Therefore, accuracy and spe...
متن کاملLead-free multilayer piezoelectric transformer.
In this article, a multilayer piezoelectric transformer based on lead-free Mn-doped 0.94(Bi(12)Na(12))TiO(3)-0.06BaTiO(3) ceramics is presented. This piezoelectric transformer, with a multilayered construction in the thickness direction, is 8.3 mm long, 8.3 mm wide, and 2.3 mm thick. It operates in the second thickness extensional vibration mode. For a temperature rise of 20 degrees C, the tran...
متن کاملHigh Performance Lead-free Piezoelectric Material
Lead has recently been expelled from many commercial applications and materials (for example, from solder, glass and pottery glaze) owing to concerns regarding its toxicity. Lead zirconium titanate (PZT) ceramics are highperformance piezoelectric materials, which are widely used in sensors, actuators and other electronic devices; they contain more than 60 weight per cent lead. Although there ha...
متن کاملPiezoelectric Active Humidity Sensors Based on Lead-Free NaNbO3 Piezoelectric Nanofibers
The development of micro-/nano-scaled energy harvesters and the self-powered sensor system has attracted great attention due to the miniaturization and integration of the micro-device. In this work, lead-free NaNbO₃ piezoelectric nanofibers with a monoclinic perovskite structure were synthesized by the far-field electrospinning method. The flexible active humidity sensors were fabricated by tra...
متن کاملSpotlight on the July 11 issue.
Recurrent thromboembolic events after ischemic stroke in patients with cancer The authors identified 263 patients with active systemic cancer diagnosed with acute ischemic stroke at a cancer center. Despite a median survival of 84 days, 90 patients had 117 recurrent thromboembolic events. Patients with acute ischemic stroke with active cancer faced a substantial short-term risk of recurrent str...
