A cardiac pacemaker is a small device placed inside the chest to help control the heartbeat. It sends electrical signals to the heart muscles to make them contract regularly and at the right pace. Full definition
«For clinical purposes, the current achievement will benefit the development of self - powered cardiac pacemakers as well as prevent heart attacks via the real - time diagnosis of heart arrhythmia. (sciencedaily.com)
«Such a battery is definitely not suitable for use in mobile phones or electric vehicles, but it may target high - end applications with special requirements, such as the power source for implantable cardiac pacemakers.» (sciencedaily.com)
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.
