   Author : Hithesh K Gatty; Göran Stemme; Roxhed Niclas; Anita Lloyd Spetz; KTH; []
   Keywords : MEMS; gas sensors; electrochemical; nitric oxide; hydrogen sulphide; nafion; nano;

   Abstract : This thesis describes novel microel ectromechanical system (MEMS) based electrochemical gas sensors and methods of fabrication.This thesis presents the research in two parts. In the first part, a method to handle a thin silicon wafer using an electrochemically active adhesive is described. READ MORE

4. 2. Towards Unconventional Applications of Wire Bonding

   Author : Stephan Schröder; Frank Niklaus; Michael Mayer; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Micro-electromechanical systems MEMS ; heterogeneous 3D integration; wire bonding; wire integration; transfer wafer bonding; nondispersive infrared gas sensing; low-stress packaging; shape memory alloy SMA ; infrared IR emitter; through silicon via TSV ; ethanol sensing; nitric oxide gas sensing; wafer-level; chip-level; Kanthal; nickel chromium NiCr ; Electrical Engineering; Elektro- och systemteknik;

   Abstract : This thesis presents novel heterogeneous integration approaches of wire materials to fabricated and package MEMS devices by exploring unconventional applications of wire bonding technology. Wire bonding, traditionally endemic in the realm of device packaging to establish electrical die-to-package interconnections, is an attractive back-end technology, offering promising features, such as high throughput, flexibility and placement accuracy.

5. 3. Heterogeneous Photolytic Synthesis of Nanoparticles

   Author : Oscar Alm; Klaus Piglmayer; Uppsala universitet; []
   Keywords : Chemistry; LCVD; Nanotechnology; Metallocene; Magnetic; Photolysis; OES; tungsten oxide; gas sensing; Kemi;

   Abstract : Nanoparticles of iron, cobalt and tungsten oxide were synthesised by photolytic laser assisted chemical vapour deposition (LCVD). An excimer laser (operating at 193 nm) was used as an excitation source. The LCVD process, was monitored in situ by optical emission spectroscopy (OES). READ MORE

   Abstract : Interdisciplinary research between medicine and microsystem engineering creates new possibilities to improve the quality of life of patients or to further enhance the performance of already existing devices. In particular, microsystems show great potential for the realization of biosensors and sampling devices to monitor bioanalytes with minimal patient discomfort. READ MORE

7. 5. Laser Sensing for Quality Control and Classification – Applications for the Food Industry, Ecology and Medicine

   Author : Patrik Lundin; Atomfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2014:Lundin;

   Abstract : Monitoring constitutes a cornerstone, both for efficient control of optimized industrial processes and for obtaining knowledge about non-controlled, natural phenomena. This thesis is all about monitoring, or measurements. In this case the primary information is gathered with light, and in a non-intrusive, and usually a stand-off or remote way. READ MORE
