1. Inkjet printed piezoelectric energy harvesters based on self-assembly of diphenylalanine peptide
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : 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. LÄS MER
2. Direct writing metal-freebio-organic piezoelectricenergyharvester
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The project is about piezoelectric energy harvesters and piezoelectric bio-organic materials.Nowadays, various kinds of energy harvesters based on micro or nano materials are appliedinmanyelectronic applications, such as wearable devices and electricity generators.

3. Piezoelektrisk taktilåterkoppling i industriellabildskärmsdatorer
Kandidat-uppsats, Uppsala universitet/Institutionen för elektroteknikSammanfattning : This project studies how tactile feedback can be implemented in existing CrossControl products,in this case the V1200-display computer. The main purpose of this function is to minimizedistraction for the user by implementing tactile feedback which creates the possibility for theuser to use the device without looking at the display.

4. Application of Lamb waves using piezoelectric technique for structure health monitoring
M1-uppsats, KTH/Hälsoinformatik och logistikSammanfattning : Structural health monitoring (SHM) is damage detection strategy for aerospace, civiland mechanical infrastructure. This project tries to show that Lamb waves, that are being generated and sensed with piezoelectric transducers, can be used for damage detection in a SHM system. LÄS MER
5. Alignment of Image Sensor using Piezoelectric Crystals
Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknikSammanfattning : The use of piezoelectric crystals as a way to achieve automatic alignment of an image sensor in a camera was investigated in collaboration with Axis Communications AB. Piezoelectric crystals can be created into different configurations, piezoelectric stacks being one of the simpler ones. LÄS MER
