#Smart sensors that harvest power from sun heat or vibrations European researchers have developed advanced energy harvesting technology that allows wireless sensor networks to power themselves from the sun, heat or vibrations.

wireless sensor networks promise to make our lives more comfortable, safer and more productive. But while many of the challenges to deploying networks of tiny sensor devices have been addressed, one key issue remains:

how to power them. Like any electronic device, sensors need energy to operate. Until now this has largely been solved by hooking them up to the grid

or using batteries, but both approaches have considerable drawbacks. Grid-connected sensors need cables, limiting where they can be used,

and contribute to electricity consumption and CO2 EMISSIONS, while battery-powered ones only last as long as their battery life.

But what if sensors could harness energy directly from their environment from the sun, from ambient heat, from radio waves or vibrations?

The result would be sensors and sensor networks that can be set up anywhere with ease

and in theory would operate perpetually with little or no maintenance or environmental impact. And that is precisely what a team of EU-funded researchers are achieving in the SWAP('Symbiotic Wireless Autonomous Powered system')project.

and expertise to develop the next generation of innovative, autonomously powered wireless sensors. n recent years,

wireless sensor networks have enjoyed a tremendous upsurge and the field has reached a level of maturity, says Professor Michele Rossi from Consorzio Ferrara Ricerche and the University of Padova,

testing and deploying novel technologies that enable sensors to use solar and thermal energy as well as radio waves and vibrations to power themselves.

the SWAP team has developed an advanced sensor platform to validate the approach, and the industrial partners are incorporating the algorithms and hardware innovations into commercial products.

For example, autonomous sensor networks that can be deployed quickly and easily anywhere will greatly improve disaster and emergency management,

Sensor networks already play a crucial role in environmental weather and climate monitoring. Making them better will serve to improve the efficiency of such applications.

Each water-bag is equipped with integrated sensors, powered by a solar cell located on the flat top of the container.

#Sensor device grabs energy in odd places University of Washington Posted by Michelle Ma-Washington on September 4 2014scientists have built a new power harvester that uses natural fluctuations in temperature

The device harvests energy in any location where these temperature changes naturally occur powering sensors that can check for water leaks

This powers sensors that also are placed on the bellows and data collected by the sensors is sent wirelessly to a receiver.

A number of battery-free technologies exist that are powered by solar and ambient radio frequency waves.

or inside a wall and sensors would be tuned to check for water leaks. Similarly when used inside a bridge the sensors could detect any cracks forming or structural deficiencies.

In both cases the sensors would send a signal to the nearby powered receiver. A temperature change of only 0. 25 degrees Celsius creates enough energy to power the sensor node to read

and send data wirelessly to a receiver 5 meters away. That means any slight shift in an office building s air conditioning or the natural outside air temperature during the course of a day would be more than enough to activate the chemical in the bellows.

The technology uses temperature changes over time as its power source. Devices called thermoelectric generators also leverage varying temperatures for power

#Tiny water sensor embedded in plant stems Cornell University Posted by Krishna Ramanujan-Cornell on October 14 2013researchers are completing soil tests on a water sensor within a fingertip-sized silicon chip

They hope to mass produce the sensors for as little as $5 each. Crop growers wine grape and other fruit growers food processors and even concrete makers all benefit from water sensors for accurate steady and numerous moisture readings.

But current sensors are large may cost thousands of dollars and often must be read manually.

The new chip which is a hundred times more sensitive than current devices is fitted with wires that can be hooked up to a card for wireless data transmission

Such inexpensive and accurate sensors can be spaced strategically in plants and soil for accurate measurements in agricultural fields.

While growers can use the sensors to monitor water in soils for their crops civil engineers can embed the chips in concrete to determine optimal moisture levels as the concrete cures. ne of our goals is to try

The sensors make use of microfluidic technologyâ##developed by Abraham Stroock associate professor of chemical and biomolecular engineeringâ##that places a tiny cavity inside the chip.

This means that bees and their stingers could become important to making better environmental sensors.

The new sensors are hypersensitive to explosives with the ability to detect even single molecules of the chemicals,

The sensors can provide experts with a ingerprintof each explosive as well as the state of its breakdown.

But the sensors aren just useful for explosives the researchers found that the coated nanotubes can also detect two pesticides that contain nitro-aromatic compounds.

This means the sensors can be useful not only to anyone from airport security officials to military troops,

but also could be useful environmental sensors. It certainly an interesting use of venom especially after we recently saw that scorpion venom can be used to create pesticides.

Strano has filed for a patent on the sensor, and the team is still working out a compression system to ensure that any molecules in the air come into contact with the tubes

But the team is hopeful that the sensors could become a commercial product in the near future.

A small Photo Voltaic solar panel provides power for the micro controller, sensors, various valves, etc.

That s important for the battery and other electronics and sensors. Once the robot can stay aloft on its own,

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.
