Imagine a world where wireless devices are as small as a grain of salt. These miniaturised devices have sensors, cameras and communication mechanisms to transmit the data they collect back to a base in order to process. Today, you no longer have to imagine it: microelectromechanical systems (MEMS), often called motes, are real and they very well could be coming to a neighbourhood near you. Whether this fact excites or strikes fear in you it’s good to know what it’s all about.
What can smart dust do?
Outfitted with miniature sensors, MEMS can detect everything from light to vibrations to temperature. With an incredible amount of power packed into its small size, MEMS combine sensing, an autonomous power supply, computing and wireless communication in a space that is typically only a few millimetres in volume. With such a small size, these devices can stay suspended in an environment just like a particle of dust.
3D printing on the microscale
Since the components that make up these devices are 3D printed as one piece on a commercially available 3D printer, an incredible amount of complexity can be handled and some previous manufacturing barriers that restricted how small you can make things were overcome. The optical lenses that are created for these miniaturised sensors can achieve the finest quality images.
Practical applications of smart dust
The potential of smart dust to collect information about any environment in incredible detail could impact plenty of things in a variety of industries from safety to compliance to productivity. It’s like multiplying the internet of things technology millions or billions of times over. Here are just some of the ways it might be used:
Disadvantages of smart dust
There are still plenty of concerns with wide-scale adoption of smart dust that need to be sorted out. Here are a few disadvantages of smart dust:
Many that have reservations about the real-world implications of smart dust are concerned about privacy issues. Since smart dust devices are miniature sensors they can record anything that they are programmed to record. Since they are so small, they are difficult to detect. Your imagination can run wild regarding the negative privacy implications when smart dust falls into the wrong hands.
Once billions of smart dust devices are deployed over an area it would be difficult to retrieve or capture them if necessary. Given how small they are, it would be challenging to detect them if you weren’t made aware of their presence. The volume of smart dust that could be engaged by a rogue individual, company or government to do harm would make it challenging for the authorities to control if necessary.
As with any new technology, the cost to implement a smart dust system that includes the satellites and other elements required for full implementation is high. Until costs come down, it will be technology out of reach for many.
What should you do to prepare?
The entities who have led the development of smart dust technology since 1992 and large corporations such as General Electric, Cargill, IBM, Cisco Systems and more who invested in research for smart dust and viable applications believe this technology will be disruptive to economies and our world.
At the moment, many of the applications for smart dust are still in the concept stage. In fact, Gartner listed smart dust technology for the first time in its Gartner Hype Cycle in 2016. While the technology has forward momentum, there’s still quite a bit to resolve before you will see it impacting your organisation. However, it’s important to pay attention to its trajectory of growth, because it’s no longer the fodder of science fiction. We might not know when it will progress to the point of wide-scale adoption, but we certainly know it’s a question of when rather than if.
