#Why Bluetooth use is on the rise Bluetooth has been with us for around 15 years.

Named after Denmark's King Harald Bluetooth Blatand, who reigned in the 10th century AD, it is a technology that everyone is aware of on their computers and phones,

and predictable technology,#says Professor Roch Guerin, Chair of Computer science and Engineering at Washington University, St louis."Bluetooth targets lower transmission ranges and data rates than wi-fi,

Bluetooth Smart, launched in 2011, includes a smarter power management system that allows it to turn on,

As a result, machines using Bluetooth that previously ran for a few months on a coin cell battery,

"Bluetooth classic is for sending steady streams of voice and audio,#says Suke Jawanda, Chief Marketing Officer of the Bluetooth Special interest Group (SIG),

which owns and licenses Bluetooth technology.""Bluetooth Smart is about sending packets of bits and data to applications.#

#Life changinghealthcare is cited frequently as one area that hasn't witnessed the radical transformations underway elsewhere as a result of the ongoing digital mobile revolution.

The growth of novel personal medical sensing technologies, many of which use Bluetooth, could soon change this.

Earlier this year, a Silicon valley-based start-up called Scanadu sought to raise $100, 000 on the crowd-funding site Indiegogo.

This data is transmitted via Bluetooth to users'phones or tablets. With recent advances in technology such as Bluetooth, we are now able to build medical devices that weren't possible just a decade ago#.

#at an affordable price using existing infrastructure of smart phone telecoms#says Scanadu's CEO Walter de Brouwer."

which is sent wirelessly via Bluetooth to an Android app, can be forwarded automatically to doctors. Bluecell is still a few years from commercialisation."

"We chose Bluetooth because of its wide distribution in consumer devices, #says Jacopo Olivo, one of the researchers."

"It's an interesting way that Bluetooth can interact with the biotech industry.##Other personal health sensors that use Bluetooth include the Cardiopad,

an electrocardiography (ECG) machine developed to monitor heart activity in patients in remote areas of Cameroon,

and sends that information directly to an ipad app via Bluetooth. By cross-checking this data against a database

Sensors could be linked via Bluetooth to sprinkler systems to automatically optimise moisture levels. The ability to use just the right amounts of water and fertiliser to produce a good harvest without wasting resources can improve crop yields and rural incomes.

Bluetooth is also being used to help those in agriculture in other ways. Kenyan mobile tech company Virtual city has developed Agrimanagr

electronic scales are used to transmit the weight of produce via Bluetooth to a mobile phone which records this in farmers'accounts on a cloud-based server.

#This system could of course be done without Bluetooth, but being wireless makes it easier.""Out in the rural areas,

With Bluetooth, our devices do that, and can work for 12 hours without electricity.##Bluetooth can also provide new ways of communicating in rural settings where internet access is unavailable or out of reach for the poor.

Gary Marsden, a computer scientist at the University of Cape town, developed Big board, an electronic notice board that disseminates information wirelessly and for free.

and send it via Bluetooth to a nearby device which sends them the information they want.

This includes a solar-powered phone charging station and a Bluetooth-based local version of Dropbox

Bluetooth Smart, like its older sibling, may be a relatively straightforward radio wave-based transmission technology. But as we devise more and more ways to benefit from ever greater connectivity between the people, other living organisms, objects and our environments,

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,

The new research harnesses technological advances in wireless networking, environmental sensors and soil water movement models.

The team tested the wireless charging system in a pig and used it to power a tiny pacemaker in a rabbit.

and efficacy requirements for using this wireless charging system in commercial medical devices. But it has the potential to eliminate bulky batteries

Either way, far-field electromagnetic waves have been ignored as a potential wireless power source for medical devices. Near-field waves can be used safely in wireless power systems.

Then there are a whole host of issues to work out dealing with wireless communications s

Collars with GPS, RFID and biometrics can automatically identify and relay vital information about the livestock in real time.

however, wants to make it easy as running an app and pairing a bluetooth dongle. The SCIO is a handheld device that pairs with a smartphone through Bluetooth LE being developed by Consumer Physics

an Israel-based startup funded by Kholsa Ventures. It based on near-infrared spectroscopy, which means it reflects light onto an object,

When trialed in a base station last year Eta Devices module became the first transmitter for 4G LTE networks to achieve an average efficiency greater than 70 percent Dawson says.

Eta Devices has entered also conversations with major manufacturers of LTE-enabled smartphones to incorporate their chips by the end of next year.

But by adjusting that voltage continuously ET efficiency falls apart for 4G LTE and 802. 11ac (Wifi) wireless standards even up to 20 MHZ bandwidth.

ETADVANCED in contrast already accommodates ultrahigh bandwidths used by newer communication standards such as LTE Advanced (up to 80#megahertz) and the next-generation Wifi standard (up to 160 megahertz).

) Prepping for future communication standards is one thing that s helped the company thrive Dawson says.

and the information sent back via wireless communications. Detecting leaks by sensing a pressure gradient close to leak openings is a novel idea

and integrate it with cells and cellular networks at the whole-tissue level. This could get around a lot of serious health problems in neurodegenerative diseases in the future."

#Device Could Harvest Wasted Energy From Wi-fi, Satellite Signals A wireless device developed by researchers at Duke university that converts microwaves into electricity could eventually harvest Wi-fi or satellite signals for power according to its creators.

It could also one day be built into cell phones to let them charge while not in use they say.

While similar devices, known as wireless capsule endoscopes, have been created in the past, the TE is notable for its soft tail,

"Other key applications include"wireless power transfer--directly adaptable to power remote devices such as RFID devices and tags or even remote devices in general,"Ramahi noted.
