At Google’s ‘Solve for X’ conference, Utah startup Chamtech introduced a spray-on antenna that could be an interesting development in improving cellphone reception.
The signal booster in a can apparently covers a surface in nanocapacitors that align themselves to create a sort of wireless antenna. The company claims the product would work on a number of surfaces including walls, trees, clothing, even underwater.
Physorg reports that the company has conducted a number of tests, including one where they were able to send a VHF signal up to 14 miles away using only a tree that had been sprayed. The spray-on antenna could reportedly make cellphones work with 10% better efficiency. A “Spray On Antenna Kit” is available from the company’s website and anyone interested can call for pricing information. Chamtech hopes its product could be used by mobile phone and medical device manufacturers, as well as the government. The company’s CEO, Anthony Sutera, gives a more detailed explanation of the spray-on antenna in the video below:
