ABSTRACT

Vehicles have widely been used for different purposes in daily life and industry for more than a century. Fuel efficiency and alternative fuel sources have been the most important topics in the automotive industry since the beginning of the industry. Social, financial, and environmental concerns related to the sustainability of energy resources have encouraged research on how to reduce CO2 emissions from vehicles and have brought forward studies on waste energy harvesting methods from vehicles. Particularly with the developments in electric cars in the last 10 years, although a lot of work has been done on the charging life of the battery as the biggest challenge, on the other hand, renewable energy harvesting systems have started to be discussed. Tires, suspensions, bumpers, fenders, etc., are parts in a vehicle that can harvest potential waste energy. High-frequency waste mechanical pressure or waste vibration is convenient to be recovered by piezoelectric and triboelectric systems. These types of works aim at the improvement on charge life of vehicle batteries. In this chapter, studies and inventions about triboelectric and piezoelectric energy harvester usage on vehicles will be discussed.
