Two-dimensional Antenna Converts Wi-Fi Signals into Electricity

• Scientists from MIT (Massachusetts Institute of Technology) have developed a two-dimensional antenna system which is totally based on existing devices called rectifying antennas, or rectennas.
• For this new design, the team members made the rectifier (the component that converts the current) – out of Molybdenum Disulfide (MoS2).
• The Molybdenum Disulfide (MoS2) rectifier can capture and convert up to 10 GHz of wireless signals with an efficiency of about 30 per cent which is much higher than other flexible designs, and much faster as compared to other designs.
• A relatively small amount of electricity is also generated which finally produce about 40 microwatts from about 150 microwatts of Wi-Fi power.
