Innovations through hair-thin optical fibres

Study shows what miniaturised optical filters make possible

22-Jan-2021 - Scientists at the University of Bonn have built hair-thin optical fibre filters in a very simple way. They are not only extremely compact and stable, but also colour-tunable. This means they can be used in quantum technology and as sensors for temperature or for detecting atmospheric gases. The ...

New cellulose-based material gives three sensors in one

A multiparameter Pressure-Temperature-Humidity Sensor based on Mixed Ionic-Electronic Cellulose Aerogels

28-Mar-2019 - Cellulose soaked in a carefully designed polymer mixture acts as a sensor to measure pressure, temperature and humidity - at the same time! The measurements are completely independent of each other. The sensor may be highly significant in fields such as robotics, healthcare and security. The ...

Quantum thermometer or optical refrigerator?

26-Jun-2017 - In an arranged marriage of optics and mechanics, physicists have created microscopic structural beams that have a variety of powerful uses when light strikes them. Able to operate in ordinary, room-temperature environments, yet exploiting some of the deepest principles of quantum physics, these ...

Scientists have created a ceramic, resistant to extreme temperatures

22-Aug-2016 - Physicists and technicians of the TSU and Institute of Strength Physics and Materials Science SB RAS are developing experimental samples of ceramics that are resistant to extreme temperatures. The scientists aim to invent a material that can withstand up to 3,000 degrees Celsius. The new product ...

The world's tiniest temperature sensor is powered by radio waves

10-Dec-2015 - Researchers at Eindhoven University of Technology (TU/e) have developed a very tiny wireless temperature sensor that is powered in a very special way: from the radio waves that are part of the sensor's wireless network. This means that the sensor needs not even a single wire, nor a battery that ...

BMBF Project “Polytos2: Printed Organic Circuits and Memory” successfully completed

04-Sep-2014 - After two years of intense collaboration with nine other consortium partners Merck, the consortium leader, has successfully completed the Polytos2 project funded with a sum of EUR 4.8 million by the German Federal Ministry of Research and Education (BMBF). Within the scope of this project, Merck ...

With carbon nanotubes, a path to flexible, low-cost sensors

Potential applications range from air-quality monitors to electronic skin

27-Sep-2013 - Researchers at the Technische Universitaet Muenchen (TUM) are showing the way toward low-cost, industrial-scale manufacturing of a new family of electronic devices. A leading example is a gas sensor that could be integrated into food packaging to gauge freshness, or into compact wireless ...

Sensirion moves into a new production building in Switzerland

03-Aug-2011 - Sensirion inaugurated its new production building in mid-July 2011. After eight months of construction, the newly purchased production plant in Stäfa, Switzerland, situated just a few hundred meters from the main building, was ready for occupancy. With the purchase and renovation of the building, ...

Energy-autonomous sensors in logistics: continuous control of perishable goods

14-May-2010 - The safety and quality in the food supply of today’s globally organized and networked supply chain is everything else than warranted. More than 50% of all foodstuffs are spoiled in the transport routes; alone in Great Britain this makes up 17 million tons and approximately 20 billion Euros. ...

Printable sensors

05-Mar-2010 - In future every home will have one: electronic devices that you can control just by pointing a finger. To turn this vision into reality the 3Plast research consortium is developing special sensors that can be printed onto plastic film and affixed to objects. The cellphone is switched off but ...
