#Wearable sensor clears path to long-term EKG EMG monitoring Researchers from North carolina State university have developed a new, wearable sensor that uses silver nanowires to monitor electrophysiological signals, such as electrocardiography
The new sensor is as accurate as the"wet electrode"sensors used in hospitals, but can be used for long-term monitoring
and is more accurate than existing sensors when a patient is moving. Long-term monitoring of electrophysiological signals can be used to track patient health or assist in medical research,
Electrophysiological sensors used in hospitals, such as EKGS, use wet electrodes that rely on an electrolytic gel between the sensor
and the patient's skin to improve the sensor's ability to pick up the body's electrical signals.
However this technology poses problems for long-term monitoring, because the gel dries up-irritating the patient's skin and making the sensor less accurate.
The new nanowire sensor is comparable to the wet sensors in terms of signal quality, but is a"dry"electrode-it doesn't use a gel layer,
so doesn't pose the same problems that wet sensors do.""People have developed other dry electrodes in the past few years,
and some have demonstrated the potential to rival the wet electrodes, but our new electrode has better signal quality than most-if not all of the existing dry electrodes.
"The sensors stem from Zhu's earlier work to create highly conductive and elastic conductors made from silver nanowires,
The new sensor is also more accurate than existing technologies at monitoring electrophysiological signals when a patient is in motion."
"The silver nanowire sensors conform to a patient's skin, creating close contact, "Zhu says.""And, because the nanowires are so flexible,
the sensor maintains that close contact even when the patient moves. The nanowires are also highly conductive,
"The new sensors are also compatible with standard EKG -and EMG-reading devices.""I think these sensors are essentially ready for use,
"Zhu says"The raw materials of the sensor are comparable in cost to existing wet sensors,
but we are still exploring ways of improving the manufacturing process to reduce the overall cost

But, to do that, you need a different sensor, Kranz explained. For this application Elbit Systems adapted a commercial sensor developed by Lifebeam, an Israeli start-up company that developed such a sensor to monitor peak performance for extreme sportsathletes such as marathon runners, bicyclists and mountain climbers.
The sensor measures oxygen concentration in the blood, heartbeat and blood perfusion (the volume of blood that flows through to the tissues.

#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.

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.
