Green electronics - new sensors and electronic applications to support sustainability
VTT’s Green Electronics Technology provides solutions that are well addressed to the broad needs of an energy-efficient society. Together with its other green technology areas, VTT is in a position to address the needs of industry and users in a holistic way. VTT has already developed several solutions for its customers which allow them to expand their businesses in the strongly increasing business arenas of green technology.
Solutions exploiting electronics are able to improve the energy efficiency of goods and services throughout their life cycles. The benefits include improved logistics and reduced waste in production, better efficiency of industrial processes, lower cost of ownership through widespread measurement solutions, improved access to services using various wireless connectivity solutions, more energy-efficient lighting, more environmental-friendly transport of people and goods and more efficient recycling based on information embedded in goods.
VTT’s scientific and technological focus on green electronics technology
VTT’s focus is on high performance sensors, optical instruments, and printed intelligence in electronics and micro technologies. These focus areas are well addressed to the broad needs of an energy-efficient society.
VTT’s key offering
Sensor solutions for energy efficient production
On-line measurement of emissions using various optical measurements in energy plants makes it possible to maintain optimal burning conditions depending on the contents of the fuel material. Condition monitoring of critical machines using various process-specific sensors enable both on-line monitoring as well as predictive measurements which help to avoid down times and to optimise maintenance breaks. VTT develops solar cell technology using roll-to-roll manufacturing technology which is well suited for large-area solar panels.
VTT provides intelligent accumulator solutions for monitoring electronics which is critical for electrical and hybrid vehicles. Energy-efficient smart grids exploit sophisticated ICT solutions to optimise the use of electricity, to avoid peaks in the demand of electricity, and to make grids bidirectional thus allowing distributed energy production.
Energy efficient lighting and housing
The new LED technology can be used to markedly increase the energy efficiency of lighting. Efficiency depends on the diodes, their driving circuits, packaging of the lighting modules, and the control of lighting. VTT has circuit technology that improves the efficiency of the driving circuits, packaging technology which improves the thermal management of lighting modules resulting in increased energy efficiency and life time, and control solutions to use lighting only when needed. VTT solutions can be used to prevent excessive air conditioning, for example by using distributed temperature and air quality (such as CO2) measurements.
Wireless and Internet technologies to support energy-efficient society
VTT offers technologies to build global sensor networks with location services to improve the energy efficiency of road transportation in logistics and usability of public traffic services. VTT solutions for wireless communication make it possible to have high-quality video meetings and remote presence to reduce travelling and environmentally unfriendly flight traffic in particular. Embedded sensors in mobile phones together with their connectivity to the Internet make it possible to increase the real-time awareness of consumers of environmental issues associated with various products and services that people encounter in their daily lives. This makes it possible to affect sustainable development at the global level based on individual consumer decisions.
