Working on Faraday’s law of electromagnetic induction, electromagnetic flowmeters measure flowrate on the basis of the electric potential induced when a magnetic flux interacts with flowing water. The electromagnetic coils of the flowmeter are crucial to its operation, given that the ... Read More

Hybrid piezoelectric and pyroelectric energy harvester/sensor for medical applications new

Balija Upendra1
1Department of Mechanical Engineering, Birla Institute of Technology and Science - Pilani, Hyderabad Campus, Telangana, India-500078

Piezoelectric materials are substances that can convert mechanical energy into electrical energy and vice versa. This is called the piezoelectric effect. When a piezoelectric material is squeezed or stretched, it creates an electric charge. This is because the material's atoms are ... Read More
