MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202641062140 A) filed by Sr University, Warangal, Telangana, on May 15, for 'adaptive vibration energy harvesting system.'
Inventor(s) include Dr. Shitendu Some.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "An adaptive vibration energy harvesting system, comprises of a cantilever beam 101 host a structure and a free end to vibrate, a rotating unbalanced mass assembly 103 applying a time-varying excitation force to induce vibration, a variable stiffness 104 arrangement for modifying the effective stiffness and tuning the natural frequency, an energy conversion unit 105 positioned to convert vibration-induced beam motion or strain into electrical energy, a sensor set measures vibration amplitude, vibration frequency, strain, displacement, or acceleration, a control unit 106 operatively coupled to the sensor set for determining a resonance condition based on measured vibration parameters, a actuator operatively coupled to the rotating unbalanced mass assembly 103 and the variable stiffness 104 arrangement for adjusting rotation speed and stiffness to maintain near-resonant vibration for increased electrical power generation, a energy conversion unit 105 comprises piezoelectric elements and electromagnetic transducers with continuous adaptive resonance tracking under varying vibration conditions."
