Imagine a world where every bolt that holds together the frame of the building you are in, holds together the car you drive, the planes in the air, and heavy machinery all around, is also a sensor. A vibration sensor, torque sensor, continually reporting on the stresses and strains on the structure in real-time. This is what German engineers have been working on for a number of years, and such screws and bolts are what they have now succeeded in making.
How do you set up a sensor web in a forest? Solar power is useless thanks to the canopy. Wildlife will get tangled up in the cables, as will people trying to manage the forest. Units need to be monitored for damage requiring dedicated staff on-site. If only we could fix all these problems, we could use sensor webs in remote areas... What's that? They're all fixed, you say?
German researchers have made advances in the sensor systems that detect if a window is open or closed, by using of all things, a heavily modified washing machine tumble sensor. It detects movement ofthe window flawlessly, by the exact same means.
Researchers at the University of California demonstrate how to turn thousands of private iPhones into a single real-time sensor web, with the help of a plug-in sensor, and an app that provides enough real immediate benefit to the iPhone users thatthey'll run it much of the time. In this case, air quality sensors, complementing (and exceeding) the capabilities of the traditional air quality weather stations.
A technological scent sensor that works in almost the exact same manner as a bog's biological nose has been developed by researchers at the University of California. The sensor, the size of an adult male fingerprint, uses microfluidic nanotechnology to mimic the biological mechanism behind canine scent receptors. The device is both highly sensitive to trace amounts of certain vapour molecules, and able to tell a specific substance apart from similar molecules.
A novel take on the sensor web has been unveiled by US firm Xhale incorporated, consists of a wireless network of soap dispensers, which contain sensors capable of detecting whether the hand waved under it, has recently been sanitized or not.
A new sensor, is able to differentiate true darkness from fog or smoke, for vehicle navigation. Even better, the developers have listened, and efforts to make it cheaply for all cars are well under way.
Sweeping an empty patch of ground to ensure it remains empty, seems an odd job for a complex sensor web. Yet, if a passenger jet strikes debris during landing or take off, it spells disaster for all aboard.
AMPERE is one of the many dedicated networks necessary to protect and grow a fledgeling sensor web. Looking down from space, 66 satellites monitor the Earth's electromagnetic field - and watch for spikes.
It was only a matter of time before someone took the concept of a sensor web literally, and created a smart mesh web that could cover an object and detect when and where any breaches in the web occur. That wait is now over, and the first such smart fabric now exists.
