1. 1. Using Harvested Energy to Power a Wireless System and Measure Vibrations

   M1-uppsats, Linköpings universitet/Elektroniska Kretsar och System

   Författare :Fredrik Lantz; Pontus Johansson; [2016]
   Nyckelord :energy harvesting; piezoelectrical; wireless; no battery; vibrations;

   Sammanfattning : The work described in this paper aims to test whether or not it is possible to power a system on energy harvested from vibrations and use that energy to measure how much it vibrates. The goal has been to produce a prototype system that uses that technique to discover damages on drones in an early stage. LÄS MER

3. 2. Ab initio piezoelectricity and energy landscape of Y0.375Al0.625N

   Magister-uppsats, Teoretisk Fysik

   Författare :Christopher Tholander; [2011]
   Nyckelord :;

   Sammanfattning : There is high industrial demand for materials with a high piezoelectrical response which are stable at high temperatures. A recent study on ScAlN has explained the microscopic origin of the increased piezoelectric response in the alloy and its effect on the energy landscape. Y is a promising candidate to observe the same phenomena. LÄS MER
