Breakthroughs in Sensor Technology
A conference organized by IMAGIC and TECHNET_NANO
Dates: 27 – 28 November 2013
Hosted by Acreo Swedish ICT AB and Electrum Laboratory.
The IMAGIC seminar days and Technet Nano workshops have become known as meeting places where leading actors connected with imaging and sensor technologies present the latest developments within their field.
This year, IMAGIC and Technet Nano collaborated in organizing a 2-day conference which highlighted the latest breakthroughs in sensor technology. At the conference assembled leading actors representing all phases of sensor technology from research to industrial production.
Invited speakers, both national and international, presented ground-breaking technology for imaging sensors, biosensors, physical sensors, and more, as well as descriptions of applications in which they are used.
Within the field of imaging sensors, Jean-Luc Reverchon (III-VLab, France) talked about the work being carried out at III-V lab to move short wavelength infrared detector technology from today’s standard which uses hybrid integration to an above-CMOS technology. Audun Rør (Sensonor AS, Norway) presented microbolometer technology for low-cost thermal infrared imaging, originally developed at Acreo within IMAGIC. This is presently being developed into a product at Sensonor. Professor Christer Fröjdh (Mid Sweden University) showed how spectral x-ray imaging can be used to separate and identify different materials in an object.
Nanotechnology is increasingly being utilized to realize more efficient sensors, and Professor Lars Montelius (Lund University, Sweden) showed how this can be used as an enabler for sensor applications. Sensors in which nanowires are used as sensing elements were presented by Professor Jan Linnros (KTH Royal Institute of Technology, Sweden) and Dawit Gedamu (Christian Albrechts University, Kiel, Germany).
Physical sensors measure physical properties of samples such as temperature, pressure, strain and more. Bertrand Noharet (Acreo Swedish ICT) showed how this can be achieved with the use of optical fibre sensors, and Per Björk (Acreo Swedish ICT) showed how sensors can be embedded on 3D substrates such as tool parts to prolong their lifetime.
Gas sensors can be used for emission control and environmental protection. Professor Anita Lloyd Spetz (Linköping University, Sweden) and Anders Gamfeldt (IRnova AB, Sweden) showed how SiC-FETs (silicon carbide field effect transistors) and QWIPs (quantum well infrared photodetectors), respectively, can be used to detect toxic and greenhouse gases. Also, it was shown that the SiC-FET can be used to detect nano-particles, and research work is currently under way using this technique to look into health issues associated with nano-particles.
Biosensors are becoming increasingly in demand for medical purposes among others. Professor Ramunas Valiokas (Centre for Physical Sciences and Technology, Vilnius, Lithuania) showed how molecular self-assembly can be achieved, and how self-assembled monolayers (SAMs) can be manipulated. The efficient integration of silicon technology with bound bio-substances for Lab-on-a-chip applications was presented by Assoc. Prof. Hans Sohlström (KTH Royal Institute of Technology, Sweden).
There are a vast number of applications that require sensors. Those chosen for presentation at the conference included an overview of the radiation-hard sensors needed for the planned upgrade of the ATLAS detector at CERN (Prof. Richard Brenner, Uppsala University, Sweden), and Henrik Linnarsson (Cerlic Controls, Sweden) showed how sensors can be used to automate a waste water treatment plant with economic benefits.
On-line sensor networks are becoming of increasing interest. Linda Olofsson (Acreo Swedish ICT) presented a national project, coordinated by Acreo, where water authorities, Swedish industry, institutes and universities work together to develop an on-line sensor network for the efficient and safe management of water. Joakim Eriksson (SICS Swedish ICT) followed this by showing that sensor networks can also be used to monitor objects, - a trend currently known as Internet of Things.
In addition to the technical presentations, a tour around the Electrum laboratory led by the lab manager Nils Nordell (KTH Royal Institute of Technology, Sweden) proved a popular attraction. The poster session and conference dinner also provided opportunity for networking with fellow attendees.
It proved to be an informative and interesting two day event.
