#First realization of an electric circuit with a magnetic insulator using spin waves Abstract: Researchers at the University of Groningen, Utrecht University, the Universit de Bretagne Occidentale and the FOM Foundation have found that it is possible to make an electric circuit with a magnetic insulator.
This was deemed first impossible. The circuit is realized using spin waves: wavelike perturbations in the magnetic properties of a material.
Their discovery is interesting for the development of novel, energy-efficient electronic devices, particularly integrated circuits. A device based on spin waves could theoretically operate more efficiently than ordinary electronic circuits.
The results of their research will be published online in Nature Physics on Monday 14 september. In our current electronic equipment, information is transported via the motion of electrons.
In this scheme, the charge of the electron is used to transmit a signal. In a magnetic insulator, a spin wave is used instead.
Duine from Utrecht University have succeeded to use spin waves in an electric circuit by carefully designing the device geometry.
and hence enables the spin waves to be used in an electric circuit. The spin wave circuit that the researchers built,

classical dipole patch antennas have been used.""Now, our technology introduces'metasurfaces'that are much better energy collectors than classical antennas,
"explained Omar M. Ramahi, professor of electrical and computer engineering. Metasurfaces are formed by etching the surface of a material with an elegant pattern of periodic shapes.
"Conventional antennas can channel electromagnetic energy to a load --but at much lower energy absorption efficiency levels,"said Ramahi."
"Our research enables significantly higher energy absorption than classical antennas, "Ramahi said.""This results in a significant reduction of the energy harvesting surface footprint.

GENESI puts sensors into a city's various structures to let them"communicate"their status. These sensors include ibrating strain gauges, displacement meters, pressure sensors, temperature sensors,
and soil moisture sensors.""To conserve power, they have energy harvesting capabilities, and engineers can periodically wake them up to get fresh readings from the sensors and check for any changes.
One of GENESI two pilot projects is a testbed in the tunnels of Rome underground rail system,
where wire sensors that pick up strain from vibration were placed inside certain concrete segments. Data loggers record the data,
transmitting the information to a wireless setup and relay system, which then sends it out via cell networks to a remote server.

Van der Lee says that one of his primary motivations for building Vinduino was to innovate on commercial soil monitoring systems that typically rely on readings from a single sensor.
Vinduino uses three sensors at different depths to get a better handle on the way water moves through the soil at each measurement point.

Sensor-based irrigation systems show potential to increase greenhouse profitability Wireless sensor-based irrigation systems can offer significant benefits to greenhouse operators.
Advances in sensor technology and increased understanding of plant physiology have made it possible for greenhouse growers to use water content sensors to accurately determine irrigation timing and application rates in soilless substrates.
The wireless sensor systems provide more accurate measurements of substrate moisture than qualitative methods and can save irrigation water labor energy and fertilizer.
The authors of a report published in Horttechnology said that the use of sensor-based irrigation technology can also accelerate container and greenhouse plant production time.
Sensor-based irrigation systems substitute capital for water and associated inputs such as energy labor and fertilizer the authors explained.
The scientists found that controlling irrigation using data from moisture sensors led to substantial reductions in both production time and crop losses.
Calculations showed that annualized profit under the wireless sensor system was over 1. 5 times more than under the nursery's standard practice
even if efficiency gains are not as high as those in the study controlling irrigation using wireless sensor systems is likely to increase profitability substantially.
They added that wireless sensor systems can have environmental benefits as well as the economic benefits shown in the study.
