in lager and to speed up the manufacturing process. In 2015, VTT announced that it had developed a sensor that can be attached to food packaging, which detects the spoilage of food by searching for ethanol accumulated in the packaging. In 2015, VTT conducted a study for the Finnish Air Force, which made it possible to extend the lifespan of Hornet’s high-pressure turbine wings while saving about 2.7 million euros. Electric buses developed by VTT were introduced in Helsinki Regional Transport Authority in Espoo in 2015 and Helsinki in 2016. In 2016, VTT said that it had developed a mobile application and a small accessory to detect the user’s heart arrhythmias. The product may also help prevent strokes. MetsäSpring textile fibres use ionic solutions to process yarn from bleached coniferous pulp. The Biocelsol technology developed by VTT and Tampere University of Technology uses enzymes to improve the dissolution of cellulose. The end result is similar to cotton. VTT’s spin-offs Spin-off companies have emerged from VTT’s research results, including Dispelix that develops lenses for augmented reality (AR) glasses GrainSense, which has developed a wireless, hand-held device for measuring grain quality Infinited Fibre Company, which manufactures new textile fibre from old textiles or recycled paper Iscent, which produces packaging and printing technologies Origin By Ocean aims to solve the problem of eutrophication by collecting algae from the sea and using its molecules to make emulsifiers for the food industry Paptic, which has commercialised the plastic-like paper material developed at VTT. The material can be used to replace, for example, traditional plastic bags Solar Foods, which produces protein from the air Spinnova, transforming cellulosic fiber into fiber for the textile industry Volare, which refines food industry waste and black soldier flies into protein for fish feed and pet food markets, and insect oils for the cosmetics industry. Commercialised VTT innovations VTT’s research results have also generated products. The eniferBio company produces fish feed with the help of a Pekilo mycoprotein found in VTT’s microbial culture collection. Goodwiller and VTT have developed a Promilless alcohol test for private use, which can be used to measure the blood alcohol content from saliva. Salofa has commercialised the world’s only rapid test for blue-green algae developed by VTT and the University of Turku. Recognition In October 2020, VTT won the Impact Expected category in an innovation competition for European research institutes in Brussels with an innovation that
