  1. 1. Inkjet printed piezoelectric energy harvesters based on self-assembly of diphenylalanine peptide

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Yujie Fu; [2023]
    Keywords : Inkjet printing; piezoelectric energy harvester; diphenylalanine peptide; self-assembly; Bläckstråleutskrift; piezoelektrisk energiskördare; difenylalaninpeptid; självmontering;

    Abstract : Diphenylalanine peptide (Phe-Phe or FF) is a very promising bio-material in the future wearable electronics application due to its self-assembly into nanotubes and nanoribbons with high shear piezoelectric coefficient which is comparable to traditional inorganic piezoelectric materials. In order to efficiently harvest piezoelectric response, alignment and unidirectional polarization of FF nanotubes are required. READ MORE

  4. 3. Energy Harvesting for Health Monitoring Balises : Analytical study

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Leire Carreras Orobengoa; [2021]
    Keywords : Balise; Energy harvesting; Railway signaling; Wireless communication networks;

    Abstract : Balises are transponders installed in railways. These devices are nowadays powered by means of a radiofrequency signal emitted by each running train that passes above them. It is only during this moment that the health state of the balises is checked. READ MORE

  5. 4. Automotive Energy Harvesting

    University essay from Mittuniversitetet/Institutionen för elektronikkonstruktion

    Author : Petter Haugen; [2019]
    Keywords : Vibration measurement; Energy Harvesting; Piezoelectrics; On-Board Unit;

    Abstract : 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.  .. READ MORE

  6. 5. A Study on Interface Circuits for Piezoelectric Energy Harvesting

    University essay from Linköpings universitet/Elektroniska Kretsar och System

    Author : Tang Honghao; [2018]
    Keywords : interface circuit; PEH system; switch;

    Abstract : 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. READ MORE
