New sensors duty as eyes in concrete

For some time, DTU Fotonik has been building visual fibres done of Plexiglas for opposite purposes. And recently a researchers have detected that visual fibres can be versed with sensors for measuring moisture, temperature, and load. When embedding a stretchable and durable cosmetic sensors into a concrete, they can simply duty as eyes in a concrete. The thought has resulted in a spin-out Shute.


One of a founders of a association is Kristian Nielsen, Development Engineer, and he says:

“Embedding sensors into petrify isn’t something new, though we would routinely use electrical heat sensors that are usually means of measuring one indicate and need dual cables per measuring point. Experiments have been conducted regulating potion fibres, though potion is some-more firm than cosmetic and breaks easily. Concrete is expel regulating petrify and aggregate, and during a drying process, a total risks relocating and violation a glass. Our sensor, however, can be stretched and focussed though being damaged.”

The new sensor is connected to a light source and a light analyser. When transmitting laser light into a fibre, a light penetrates a twine and is reflected by a measuring point, after that a analyser detects what has happened during a measuring point. The research continues on a computer, and a customer is afterwards means to guard a routine during home.

The association is utterly new and therefore still in a routine of documenting a continuance of a product. But a initial formula are rolling in, for instance in tie with NCC Building, one of a heading construction and skill growth companies in Northern Europe, that has expel a cosmetic twine sensor into one of their floors.

“During a construction phase, it’s really critical to keep concentration on a dampness turn of a concrete, generally if installing wooden floors over a concrete. To safeguard that a petrify has a right dampness level, we routinely take samples, though a Shut sensor complement allows us to guard a drying routine and continue a work as shortly as a dampness turn is satisfactory. If it works as intended, we will be means to save time and presumably money, and we equivocate carrying to take unchanging samples from a concrete. Another advantage is that we obtain information on a drying that we can use via a whole construction process,” says Timmi Sargentoni, Contract Manager during NCC.
