6. Automotive Energy Harvesting
Master-uppsats, Mittuniversitetet/Institutionen för elektronikkonstruktionSammanfattning : Vibration measurements conducted in three vehicles windshields are used to determine frequency content in the windshield of moving vehicles. A piezoelectric energy harvester is modeled, and used in simulations to determine output voltage and power with measured acceleration signal as input. .. LÄS MER
7. Analytical and Numerical Study of a Passive Self-Tuning Resonator
Master-uppsats, Lunds universitet/MekanikSammanfattning : Energy harvesting, from ambient vibrations, can be a very effective method for solving the problem with powering electronics were the need for constant power or regular battery replacements is a trouble or an inconvenience. But, since all energy harvesters, using mechanical vibrations, need to operate in resonance in order to generate maximal electrical output, and ambient vibrations usually do not have a constant vibration frequency, this results in the need for efficient self-tuning systems.

8. A Study on Interface Circuits for Piezoelectric Energy Harvesting
Master-uppsats, Linköpings universitet/Elektroniska Kretsar och SystemSammanfattning : A piezoelectric energy harvesting (PEH) system can harvest electrical energy from ambient vibration energy. In a PEH system, the interface rectifier circuit is critical because it converts AC from the output of piezoelectric harvester to DC that can power the load. LÄS MER
9. Energy Harvesting for Electronic Systems
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automationSammanfattning : Energy harvesting enables products to become more self-sufficient of power and offers the possibility to avoid battery exchange and power cables. The performance and applicability of the most promising or popular small scale energy harvesting technologies are investigated in this thesis. LÄS MER
10. Piezoelektrisk energiskördning för oregelbundna lågfrekventa rörelser
Uppsats för yrkesexamina på grundnivå, KTH/Skolan för informations- och kommunikationsteknik (ICT)Sammanfattning : Energiskördning är idag ett växande område och är framstående sett till hållbarhetsaspekterna. Vibrationsbaserad sådan har blivit allt populärare där man kan utnyttja mekanisk energi från olika källor till att generera elektrisk energi. LÄS MER
