Engineers develop prototype of electronic nose

A nose by any other name is a gas sensor


There’s nothing like the smell of freshly brewed coffee in the morning. But how does one measure that smell? There’s no energy in a smell to help estimate how potent the coffee might be. Instead, it’s the gases emitted from brewed coffee that contribute to the invigorating scent. The human nose ...

NTU Singapore scientists create ultra high performance flexible ultraviolet sensors for use in wearables


To enable the development of wearable devices that possess advanced ultraviolet (UV) detection functions, scientists from Nanyang Technological University, Singapore (NTU Singapore) have created a new type of light sensor that is both flexible and highly sensitive. While invisible to the human ...

Fastest sensor for heat flow tested

Relevant for alternative fuels and hydrogen


A team of researchers from the Faculty of Mechanical Engineering at Landshut University of Applied Sciences has developed a new method to measure the heat flow in combustion engines faster than before. The technique could help reduce pollutant emissions in the future. It is also relevant for the ...

Nanosphere at the quantum limit

Sensors could be immensely improved with nanospheres


Researchers at ETH Zurich have trapped a tiny sphere measuring a hundred nanometres using laser light and slowed down its motion to the lowest quantum mechanical state. Based on this, one can study quantum effects in macroscopic objects and build extremely sensitive sensors. Why can atoms or ...

Miniature material analysis sensors on the way to mass production

Senorics raises more than 8 million Euro


The Dresden high tech company Senorics has closed an 8 million € pre-series A financing round. The money allows for the necessary investments to scale the innovative material analysis sensor technology for the industrial market. The circle of investors was joined by FIDURA Private Equity as lead ...

New atomically precise graphene nanoribbon heterojunction sensor developed

Novel sensor is highly sensitive to atoms and molecules


An international research team led by the University of Cologne has succeeded for the first time in connecting several atomically precise nanoribbons made of graphene, a modification of carbon, to form complex structures. The scientists have synthesized and spectroscopically characterized ...

Voltage from the parquet

Piezoelectric wood can generate electricity through deformation


Researchers at Empa and ETH Zurich have made wood compressible and turned it into a micro-generator. When it is loaded, an electrical voltage is generated. In this way, the wood can serve as a bio-sensor - or generate usable energy. The latest highlight: To ensure that the process does not ...

Innovations through hair-thin optical fibres

Study shows what miniaturised optical filters make possible


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 ...

How does your computer smell?

Researchers create a highly sensitive biohybrid olfactory sensor


A keen sense of smell is a powerful ability shared by many organisms. However, it has proven difficult to replicate by artificial means. Researchers combined biological and engineered elements to create what is known as a biohybrid component. Their volatile organic compound sensor can effectively ...

Researchers report quantum-limit-approaching chemical sensing chip

Study shows improvements to chemical sensing chip that aims to quickly and accurately identify drugs and other trace chemicals


University at Buffalo researchers are reporting an advancement of a chemical sensing chip that could lead to handheld devices that detect trace chemicals -- everything from illicit drugs to pollution -- as quickly as a breathalyzer identifies alcohol. The chip, which also may have uses in food ...
