#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,

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,

This feature allows phones to connect to one another directly using Bluetooth or Wi-fi as an alternative to the Internet.

"Nikola Technology efficiently converts RF signals like Wi-fi, Bluetooth, and LTE into DC power using its proprietary energy harvesting circuit,
