Metal detectors are everywhere, from airports to museums to military bases, but there are only a handful of them that are actually designed to work and work very well.
This is because their basic design is fundamentally flawed, according to a new report.
The researchers from the University of Bristol’s School of Engineering, led by Prof. Dr. Richard Steedman, said that the main reason for this is that they were designed for a certain era, in the 1970s, and are now obsolete.
In their report, published in the journal Science, the team says that the metal detectors that are still in use today do not meet the “current and future demands of the society” and need to be replaced.
Prof. Steedmann said that metal detectors are being used on the street and at work and are “a vital tool for public safety”.
He told BBC News: “The problem is that most people don’t think about it, they think of it as a nuisance.
The main drawback of the current generation of metal detector technology is that it is designed to detect metal at a distance of around 10cm, compared to the much larger range of 10cm for a real metal detector. “
So the fact is that the technology for detecting metal is very primitive.”
The main drawback of the current generation of metal detector technology is that it is designed to detect metal at a distance of around 10cm, compared to the much larger range of 10cm for a real metal detector.
In addition, the current detectors are “very sensitive”, and if you put too much force on them, they can distort the image and cause damage to the detector.
To improve on this, the researchers said that they would be “very excited” to design a “battery-powered” metal detector that is “much smaller than 10cm” and can detect “minuscule” amounts of metal.
The new device would also be able to detect a “greater range of metals” compared to current metal detectors, and it could detect metals from 0.5 millimetres to 100 millimetre in size.
It would also function with less current and would last for “many, many years”.
The researchers also said that it would be possible to use a battery-powered metal detector with “no power source at all”, and that they “would be very excited” about the prospect.
This would be particularly useful for use in public spaces, which are often crowded with people who may not be aware of their presence.
The team said that in future they would like to design “a metal detector capable of detecting a variety of materials”.
“It would be a very interesting, exciting project and we would be very, very happy if the project is successful,” Prof. Schildman said.
“I’m really excited that we’ve made this progress, and that we are now able to test our work.”
