Abstract

Microelectromechanical system (MEMS) devices are dominant creative devices used nowadays in our health care system. The researcher examined the roles of microelectromechanical devices and their applications in investigation, treatment, monitoring and improvement of various human health conditions. The microelectromechanical (MEMS) is the technology of very small devices, it mages at the nano-scale in to nanoelectromechanical system and are made between 1 to 100 micrometers in size (0.001 to 0.1mm). And the devices are generally range in size from 20 micrometers (20 millionth of meter). The health is the level of functional or metabolic efficiency of a living organism. In humans, it is the general condition of a person’s mind and body, being free from illness, injury or pain. The description of Basic materials being used in fabrication and manufacturing of biomedical instruments and they function with the basic principles of biosensors whose application are geared towards improvement, investigation and monitoring of human biological system. Despite the great achievements recorded through the use of these devices, many of them are not free from certain complications such as device failure, attraction of harmful microorganisms, rejection etc.
