Emerging technologies like the ones below are interesting. They could be used for illegal eavesdropping in the future. Combining the first two could produce a wireless bug that never has to have its batteries replaced. It could also be incredibly small.
Some people say, "the bad guys are always one step ahead of us."
I say, "do your homework and you will be one step ahead of them."
Ultra-Low-Power WiFi Radio Enables IoT Devices
- Housed in a chip, it lets IoT devices communicate with existing WiFi networks.
- Housed in a chip smaller than a grain of rice.
- The radio could last for years on a single coin cell battery.
New Green Technology from UMass Amherst Generates Electricity ‘Out of Thin Air’
The laboratories of electrical engineer Jun Yao and microbiologist Derek
Lovley at UMass Amherst have created a device they call an “Air-gen.”
or air-powered generator, with electrically conductive protein nanowires
produced by the microbe Geobacter.The Air-gen connects electrodes to the protein nanowires in such a way that electrical current is generated from the water vapor naturally present in the atmosphere. “We are literally making electricity out of thin air,” says Yao.
Seeing Around Corners to Detect Object Shapes
Special light sources and sensors see around corners or through gauzy filters, enabling reconstruction of the shapes of unseen objects.
A technique was developed that enables reconstruction of images in great detail. Researchers computed millimeter- and micrometer-scale shapes of curved objects, providing an important component to a larger suite of non-line-of-sight (NLOS) imaging techniques.
Most of what people see — and what cameras detect — comes from light that reflects off an object and bounces directly to the eye or the lens. But light also reflects off the objects in other directions, bouncing off walls and objects.
