Inventor(s) include Shyam R; Yuvaraj P; Mohamed Shahin B; Shree Dharshan P; Venkatrajan V; and Rishidharan M.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The current high rate of increase in the world electricity demand has caused excessive reliance on non-renewable sources of energy like coal and petroleum, which cause massive contamination of the environment and are few in their supply, Meanwhile, tremendous quantities of mechanical energy created by the motion of people in the busy places are fully wasted. The railway stations, shopping malls, the learning institutions, bus terminals, airports, and the pedestrian walkways all experience this constant foot traffic during the day. The mechanical energy generated by these footsteps is usually lost without recovery of energy at all. Thus, it becomes necessary to have a new system that can capture and transform this wasted mechanical energy to useful electrical energy in a sustainable fashion that is environmentally friendly. -Mar-2026/34804/202641028863/Form 2(Title Page) The current invention offers a Footstep Power Generation System based on Piezoelectric Sensor, a device that will tap electrical energy of human footsteps. The system comprises of specially engineered floor tiles or platforms with piezoelectric sensors embedded in them. Mechanical pressure on the piezoelectric sensors located beneath the surface is exerted when an individual steps on the tile.-Because of piezoelectric effect, mechanical stress produced causes an electrical charge. The resulting electrical power is then gathered and fed into a rectifier circuit and used to convert the alternating power into direct current which can then be used. The corrected power is then stored in an energy store like rechargeable battery or capacitor. The resulting electrical power can be used to drive small electrical devices and applications consuming less energy like mobile phone charging stations, LED systems, emergency lighting, power banks, sensors, and information display systems. The proposed system will be developed to work 24 hours in the presence of foot traffic, which is why it is possible to produce energy during the day and night and not rely on weather conditions. The separate nature of the tiles is designed in a manner that allows the installation of its usage within an already established infrastructure like pedestrian corridors, railway tracks, shopping centers, parks, and the institutional corridors. In addition, the system is not very maintenance intensive and it has a long lasting structure that can withstand repeated foot pressure in crowded places. The suggested invention will help to preserve energy, decrease the reliance on fossil fuels, and improve the use of sustainable and renewable energy sources in urban areas by transforming otherwise wasted mechanical energy into usable electricity. In general, it can be seen that the invention is an eco-friendly, affordable, and scalable way of decentralized micro-power production through the use of human footsteps as a renewable source of energy."
