Wireless Sensor Promises Diabetics Noninvasive Blood Sugar Readings

For many diabetics, the unpleasant chore of drawing blood several times a day in order to check blood glucose levels is a part of life. Efforts to develop devices that can test blood glucose without the need to repeatedly prick fingers have faltered thus far due to questions about accuracy as well as complaints about skin irritation. One company is hoping to solve these problems with a biochemical sensor that adheres to the skin like a bandage and sends continuous blood glucose readings to a handheld wireless device.

Humdinger Wind Energy develops portable wind energy harvester

According to statistics, about 2 percent of global electricity comes from wind-powered generators, and their capacity has doubled in the past three years. However, scaling down wind turbines for use as an electronic device charger hasn’t proved fruitful, as conventional wind turbines require rotating fins and gears, which add bulk, making the device inefficient when scaled down.

Humdinger Wind Energy LLC has developed a product dubbed the MicroBelt that according to the company can power the new information age with a billion tiny harvests. The world today is monitored by millions of wireless sensors that collect a variety of information. These sensors then connect the real world with the internet world by consuming energy.

Next Generation RS485 Wireless Mesh Network System Released

Crossbow Japan Ltd., a subsidiary of MEMSIC Inc.,announced today the availability of the RS485 Wireless Mesh Network System. The System enables users to convert existing wired RS485 systems into wireless networks just by replacing the wired connections to the wireless WS-Z5000A node.

Using leading-edge wireless sensor networking technology the RS485 wireless connection offers versatility for industrial use of 1:1 or 1:N. The WS-Z5000A can be easily configured within the software enabling the user to easily adopt the WS-Z5000A into a wide range of different RS485 wired protocols.

Mini generators make energy from random ambient vibrations

Tiny generators developed at the University of Michigan could produce enough electricity from random, ambient vibrations to power a wristwatch, pacemaker or wireless sensor.

The energy-harvesting devices, created at U-M’s Engineering Research Center for Wireless Integrated Microsystems, are highly efficient at providing renewable electrical power from arbitrary, non-periodic vibrations. This type of vibration is a byproduct of traffic driving on bridges, machinery operating in factories and humans moving their limbs, for example.

'Smart' Contact Lens with Embedded Wireless Sensor for Glaucoma Treatment

STMicroelectronics, the world’s leading supplier of MEMS (Micro-Electro-Mechanical Systems) devices for consumer and portable applications, has announced that it will develop and supply a wireless MEMS sensor that acts as a transducer, antenna and mechanical support for additional read-out electronics in a breakthrough platform developed by Swiss company Sensimed AG. This solution will enable better management of glaucoma patients via earlier diagnosis and treatment that is optimally tailored to the individual patient.
Known as the SENSIMED Triggerfish®, the solution is based on a “smart” contact lens that uses a tiny embedded strain gauge to monitor the curvature of the eye over a period of, typically, 24 hours, providing valuable disease management data that is not currently obtainable using conventional ophthalmic equipment.

PhD Student Position in WSN

We are glad to announce a PhD position at the University of Trento, Italy, for doing research in WSN within the D3S group. D3S is a cross-institution group of researchers from both the university and the nearby FBK-IRST research centre, whose projects are characterised by theoretical backing and practical applicability.

Examples of projects currently ongoing include TRITon, a project on road tunnel monitoring using WSNs, and ACube, a project where a pervasive computing environment equipped with audio, video, and other types of sensors provide support for elders and people with disabilities. New PhD students are invited to participate in ongoing projects to gain experience and insight into real systems, and to identify novel, challenging problems whose solutions break new ground.

Complete info about the call, the University, the city and previous research projects from this group are available here.

Applications deadline 20 April 2010
