A review on miniature bio-implant antenna performance enhancement and impact analysis on body fluids in medical application
Abstract
Nowadays, the attention is on building an efficient and constantly evolving healthcare system for the human body is keep on increasing. Implantable devices introduced with pacemakers have become more phenomenal in the health care system nowadays. This paper discusses the recent advancements in bio-implanted antennas and various antenna structures proposed by investigators for biomedical applications. It also summarises the design need, antenna structures, dimensions, and features in the Medical Implanted Communication System band and Industrial Scientific Medical band. The antenna is implanted into the human body and embedded with a bio-medical sensor. The signal from the sensor is radiated by the antenna outside of the body to be analyzed by the receiver. Bio-implanted antennas based on microstrip structure have a negative gain (low radiation) due to body fluids. The motto of the review paper is to deliver attention for production with subjects related to Biocompatibility, Miniaturization, Biomedical sensors with implanted antenna, and increased quality of communication with an external receiver. It also highlights and focuses on the gain improvement of the microstrip antenna within the human body to get effective radiation. Moreover, the several experimental setups of the bio-implanted antenna with biomedical sensors are summarised in many biomedical applications such as glucose, deep brain stimulation, endoscopy, laparoscopy, pacemaker, temperature and blood pressure monitor.
