Wang, his Ph.D. student Yanchao Mao and collaborators from Sun Yat - sen University in China, and the University of Minnesota Duluth described their device, a mesoporous
piezoelectric nanogenerator, in the January 27, 2014, issue of the journal Advanced Energy Materials.
A research team from the Korea Advanced Institute of Science and Technology (KAIST), headed by Professor Keon Jae Lee of the Department of Materials Science and Engineering at KAIST and Professor Boyoung Joung, M.D. of the Division of Cardiology at Severance Hospital of Yonsei University, has developed a self - powered artificial cardiac pacemaker that is operated semi-permanently by a flexible
piezoelectric nanogenerator.
In addition, the flexible
piezoelectric nanogenerator could also be utilized as an electrical source for various implantable medical devices.»
The team's newly designed flexible
piezoelectric nanogenerator directly stimulated a living rat's heart using electrical energy converted from the small body movements of the rat.
