    Abstract : Gas detection is crucial in a wide range of fields and applications, such as safety and process control in the industry, atmospheric sciences, and breath diagnostics. Optical gas sensing offers some key advantages, compared to other sensing methods such as electrochemical and semiconductor sensing: high specificity, fast response, and minimal drift. READ MORE

  2. 2. Towards Unconventional Applications of Wire Bonding

    University dissertation from KTH Royal Institute of Technology

    Author : Stephan Schröder; KTH.; [2018]
    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.

    Abstract : The use of renewable wood-based fuel has been increasing in the last few decades because it is said to be carbon neutral. However, wood-based fuel, and especially used wood (also known as recycled wood or waste wood), is more corrosive than virgin wood (forest fuel), because of higher amounts of chlorine and heavy metals.
