The 'paper' antenna collects energy around it

Scientists at Georgia Tech have created a printed or plastic antenna that can collect energy around them for small electronic devices.

According to scientists, there is a large amount of electromagnetic energy around us that is not properly exploited. Thus, they use inkjet printers that use a silver nanoparticle emulsion to print sensors and radio frequency circuits onto paper or plastic, turning them into super-wide-band antennas.

These antennas can be electromagnetic filtered by radios, radios, radios ... with varying frequencies from 100 MHz to 15 GHz or higher. From there, it allows wireless sensors to capture electromagnetic currents in the surrounding air, capture energy from a wide spectrum of frequencies, convert them into direct current or store them in capacitors. power or battery.

With a current of up to 50 milliwatts, this type of antenna can provide enough power for wireless power sensors and microprocessors.
