Abstract: THIS INVENTION RELATES TO A DEVICE FOR HARVESTING ENERGY FROM UBIQUITOUS RADIO WAVES AND MORE PARTICULARLY AN ADAPTIVE RECTIFIER DEVICE (8) DESIGNED AS POWER HARVESTING CIRCUIT WHICH IS TO HARVEST ELECTRICAL ENERGY BY TAPPING THE COMMERCIALLY AVAILABLE RADIO WAVES. THE DEVICE (10) COMPRISES OF AN ANTENNA (1), A HIGH FREQUENCY TRANSFORMER (2), AN AUTOMATIC TUNING CIRCUIT (3), A CAPACITORS BANK (4), A RECTIFIER (5), A THRESHOLD LIMIT CIRCUIT (6) AND AN ADAPTIVE CIRCUIT (7). THE THRESHOLD LIMIT CIRCUIT (6) IS CONFIGURED HAVING A PREDETERMINED OUTPUT VOLTAGE AND WHEN AN OUTPUT VOLTAGE IS BELOW THAN THE PREDETERMINED VOLTAGE, THE AUTOMATIC TUNING CIRCUIT (3) STARTS SEARCHING FOR NEW SOURCE OF RADIO FREQUENCY (RF) ENERGY BY CHANGING ITS CAPACITANCE BY FEEDING A DISTINCTIVE VOLTAGE INTO THE AUTOMATIC TUNING CIRCUIT (3) VIA THE ADAPTIVE CIRCUIT (7). THE SEARCHING FOR RF ENERGIES STOPS WHEN THE OUTPUT VOLTAGE LEVEL RESUMES TO THE PREDETERMINED VOLTAGE.

Abstract: This invention relates to a device for harvesting energy from ubiquitous radio waves and more particularly an adaptive rectifier device (8) designed as power harvesting circuit which is to harvest electrical energy by tapping the commercially available radio waves. The device (10) comprises of an antenna (1), a high frequency transformer (2), an automatic tuning circuit (3), a capacitors bank (4), a rectifier (5), a threshold limit circuit (6) and an adaptive circuit (7). The threshold limit circuit (6) is configured having a predetermined output voltage and when an output voltage is below than the predetermined voltage, the automatic tuning circuit (3) starts searching for new source of radio frequency (RF) energy by changing its capacitance by feeding a distinctive voltage into the automatic tuning circuit (3) via the adaptive circuit (7). The searching for RF energies stops when the output voltage level resumes to the predetermined voltage.
