Piezoelectric shoe

Harvesting mechanical energy from human motion in day to day life is a very attractive way of creating sustainable electric energy and a piezoelectric shoe exactly does that. Since it is a wearable energy harvester, it is very convenient to use it and has many advantages which will be discussed further. It generates electricity through piezoelectric effect in the shoe and stores it in a battery which can further be used to charge your phone. When a person walks electrical energy is produced and that energy is stored in the battery.

Smart life vest

The Smart Life Vest which aims at increasing the efficiency of rescue operations in water. The primary features of the Smart Life Vest include sending automatic SOS signals containing the wearer’s GPS location to the nearest rescue station using radio or microwave signal, which will immediately alert the rescue party of an emergency. The Smart Life Vest will also produce its own power using a built-in wave generator and make use of chemicals that react with water to facilitate its auto-inflation mechanism. Both of these will increase the shelf-life of the Smart Life Vest and reduce the maintenance cost.
