1. 1. Automated High-Temperature Pressure Sensor Verification and Characterization

   University essay from Linköpings universitet/Institutionen för systemteknik

   Author : Algirdas Bartkevicius; [2023]
   Keywords : Pressure sensor; sensor verification; sensor characterization; piezoelectric sensor; dynamic pressure sensor;

   Abstract : Gas turbines are widely used in power generation. Monitoring pressure variations in the combustion chamber allows for real-time assessment of the turbines performance, and can be used to optimize combustion processes, leading to reduced emissions. READ MORE

3. 2. Alignment of Image Sensor using Piezoelectric Crystals

   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

   Author : Julia Jakobsson; Reem Chahrour Muhieddine; [2023]
   Keywords : piezo; piezoelectric; crystal; piezoelectric crystal; piezoelektrisk; kristall; piezoelektrisk kristall; camera; kamera; focus; fokus; Axis; Axis Communications; alignment; justering; prototyp; prototype; algorithm; algoritm; Technology and Engineering;

   Abstract : 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. READ MORE

4. 3. Enhancing Sensing in Nanoscale: Investigation of Smart Nanomechanical Cantilever Array

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Hiruy Michael Weldegiorgish; [2022]
   Keywords : Cantilever; AFM; Biosensor; Piezoresistive sensor; Piezoelectric actuator; Kantilever; AFM; Biosensor; Piezo -resistorer; Piezo-elektiska pådrivare;

   Abstract : In this report, a novel smart nanocantilever with self-deflection sensor using embedded piezo-resistor and self-actuation using integrated piezo-electric actuator is proposed, designed and simulated to enable highly sensitive label free biosensor and ultra-short cantilever probe for AFM applications. The smart nanocantilever comprises of a triangular Si3N4 nanocantilever (10µm long, 400nm width and 100nm thickness) connected to a multi-layer support structure (Si3N4 (100nm)/PZT (100nm)) having n-type silicon piezo resistor (7µm long ,2µm width and 20nm thickness) embedded in the Si3N4 layer in both the support structure and nanocantilever.

5. 4. Piezoelectric Guitar Tuner

   University essay from KTH/Mekatronik

   Author : Albin Boestad; Fabian Rudberg; [2021]
   Keywords : Mechatronics Tuner Guitar Piezo Arduino; Mekatronik; Stämmare; Guitar; Piezo Arduino;

   Abstract : This bachelor thesis in Mechatronics account for the process of constructing an automatic guitar tuner by means of a piezo-electric sensor, a stepper motor and Arduinobased control. The E4 - string on an acoustic guitar was used as a proxy for tuning any other possible guitar string. READ MORE

6. 5. Jet Printing Quality ImprovementThrough Anomaly Detection UsingMachine Learning

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Henrik Lind; Jacob Janssen; [2021]
   Keywords : Jet Printing; Autoencoder; Anomaly Detection; Sound; Acoustic; Machine Learning; Solder Paste; Piezoelectric Current; Self Sensing;

   Abstract : This case study examined emitted sound and actuated piezoelectric current in a solderpaste jet printing machine to conclude whether quality degradation could be detected with an autoencoder machine learning model. An autoencoder was used to detect anomalies in non-realtime that were defined asa diameter drift with an averaging window from a target diameter. READ MORE
