The often great age of bridges and the increasing volume of traffic (particularly heavy traffic) which they are expected to carry are in clear contradiction to each other. Thus the probability increases that the load-bearing capacity of a bridge decreases rapidly and often unnoticed with sometimes dire consequences.
In order to prevent such accidents, the Federal Institute for Materials Research and Testing and the Berlin-based ScatterWeb Company are currently developing a special radio-based, self-configuring measuring system. This measuring system consists of a number of identically designed sensors which are self-sustaining, need no wiring, can act as both transmitters and receivers and are equipped with a special sensor technology making long-term monitoring of buildings or engineering facilities possible. This in particular applies to buildings and structures for transport and traffic and large-scale industrial facilities, where a subsequent wiring installation is difficult or impossible.
In order to reliably monitor large or inaccessible objects over the long term, the radio range must be sufficient. The sensor unit uses strain gauges for stress analysis and contains interfaces for additional sensors. In addition, all components must exhibit a high accuracy of measurement and high energy-efficiency. The high network stability required can be ensured by the so-called multihop architecture which enables the exchange of failed modules and the integration of additional modules without interrupting the network operation.
The project is supported by the Federal Ministry of Economics and Technology and unites two partners, both of whom are in a leading position in their fields. BAM's Division "Measurement and Testing Technology, Sensors" provides its competence in the field of sensor technology, experimental structure monitoring and early damage assessment while the ScatterWeb Company is prominent in the field of self-configuring wireless mesh networking.Contact:

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
