An Indian student has invented a device that can help to protect women from attackers.
Seventeen-year-old high school student Siddharth Mandala spent years working on ElectroShoe, a pair of shoes that can electrocute attackers and help to prevent sexual assault.
Using only the basic concepts of physics learned in school, Siddharth created a unique circuit board that uses footsteps to charge itself based on a concept called the “piezoelectric effect.”
The more the user walks, the more energy is generated
The shoe harvests energy produced while walking and stores it in a rechargeable battery. When the battery is sufficiently charged, the shoe can inflict 0.1-amp “power kick” on the attacker and also sends an alert to police and family members for help.
ElectroShoe is not yet available for sale. The functional prototype of the shoe is a flip-flop that needs to be developed further to make ElectroShoe a marketable product.
