Diagnostic Biomedical Microelectromechinical Systems (Bio Mems) Essay

2214 words - 9 pages

Microsystems for automotive applications are called MicroElectroMechanical Systems (MEMS). As these parts displayed mechanical and pressure sensor systems, combining them with medicine and health care industry created the term BioMEMS (Biomedical microelectromechanical systems) [6]. This paper talks about the different kinds of diagnostic BioMEMS used nowadays. Diagnostic systems mentioned here are Miniature Mass Spectrometers, Micro fluid Processors, Wireless capsule endoscopy and Protein-Based Biosensors. And finally it discusses the material that should be used to make this BioMEMS which are silicon coated surfaces with 50 nm of titanium.IntroductionBioMEMS are Biomedical Microelectromechanical Systems are devices that are used in Biomedicine and Bioengineering. These are non-invasive devices that are used in the diagnoses and curing of diseases. A BioMEM can be imagined to be a device which when inserted into a blind individual's retina, can restore his vision. These can even be thought of as devices which when inserted deep inside the body can detect heart failures. They use the same design and manufacturing principles as computer chips. This system is used to design small medical sensors, actuators which are mechanical devices used for moving and controlling mechanisms, and motors. Some of these devices are used in surgery and in diagnosis of common diseases. Examples of BioMEMs include DNA analysis tools such Microarrays. This tool is used to analyze DNA structures and identify mutated genes and are eventually used in disease screening. Other examples of BioMEMs are Camera Pill and Biosensors. The Camera Pill is explained in detail, in Wireless Capsule Endoscopy, which is a diagnostic technique. Two types of sensors that are most common are the pressure and glucose sensors. Sensing, and ultimately controlling, the pressure of various body fluids is the key to improving human health. Examples of the fluid in out body are the blood, fluid in the ear, eye, spinal cord, urine, etc.A glucose sensor patch was developed by a professor in MIT. His name is Anand Gadre, and according to him, this sensor patch can read with absolute accuracy the individual's glucose and lactate levels with the help of some enzymatic detection techniques, within a few seconds of placing the patch, and without breaking open the skin. Figure 1 depicts this glucose sensor patch.Fig. 1. Sensor Patch on human arm – Glucose TestingSome of the improvements that are seen in the health care industry after adopting these devices are:•Early diagnosis of the disease.•Less trauma.•Faster recovery.•More economic.This paper discusses the various types of diagnostic BioMEMS used in the health care industry to facilitate patients with the best therapy. Three widely growing areas under this system are diagnostic microsystems, surgical microsystems and therapeutic microsystems.The technology used in the making of silicon chips is also used in the fabrication of...
