Medical Sensors: An Imminent of Healthcare Industry

A broad intersection of the biotechnology and information technology sector have led to the introduction of sensors in the medical field. Electronic systems used in medical field such as equipment, probes, and devices rely on signals sent by sensors for various control activities, treatment, and accurate diagnosis. Sensors are increasingly being used in medical devices with the aim of making safer and effective medical solutions. Sensors are incorporated into medical devices such as lenses, blood monitoring devices, and medical implants, for the detection of chemical, physical, and biological signals radiated by the human body. Global medical sensors market includes some of the leading pharmaceutical and biotechnology industry players such as Bayer AG, Philips Healthcare, GE Healthcare, and Abbott Laboratories, among others. These players have started the development of portable ECG devices for cardiac patients, which avails the facility of home use to the patients. 

Medical Sensors Market

The sensors exhibit the role of monitor, detector, and recorder for the activities performed by the human being. It monitors various physical properties of the body, which includes pressure, temperature, sound level, vibration, and flow rate of liquids and gases, among others. Sensors converts the electronics-based signal received from medical equipment to various forms of stimuli and back to electrical signals for the disease analysis. The researchers are rigorously developing thin sensors for the global medical sensors market. A sensor sizing 50 times thinner than a human hair has enabled doctors and patients to manage and control chronic diseases such as diabetes. These thin medical sensors can accurately measure small concentration of gases known as metabolites, which are generally discharged through skin or breadth, and assists in the monitoring of the patient’s health. Researchers of Australian National University (ANU) have developed tiny optical sensors that can be used in wearable medical devices, which in turn, assists doctors in the diagnosis of patient’s health in real-time. Moreover, the smart watches and bracelets can detect the number of steps taken by an individual in a day along with the monitoring of heart rates. 

Recent innovations in the medical sensors market 

o Smart Contact Lens: Google X – It comprises tiny wireless chip, antenna, and miniaturized glucose sensor, which accurately monitors the glucose of diabetic patients using bodily fluids such as tears. 

o Non-Invasive Blood Monitor: Digital Tattoos – These tattoos are needle-less, painless, and sensor-laden transdermal patch or ink. The tattoo can read blood levels of glucose, sodium, kidney functions, and balancing of electrolyte from a smartphone. 

o Ingestible Drug Delivery System: Electronic Pills – These ingestible pills are swallowed by the patients suffering from gastrointestinal cancer. The pills contain microprocessor, thermometer, radio transmitter, pH sensors, fluid pump, and drug reservoir. The ingestible pills find its way to the tumour, releases the drug, and flows out from the body. 

o Implantable Brain Activity Sensor: Wireless Sensors – These sensors can be fully implanted in the brain. The product offers wireless data monitoring for over a year during the early stage tests. 

o Non-Invasive Tubing Pressure Sensors: Disposable Sensors – The product is made up of anodised aluminium electronic sensor, offers a contamination-free and one-time use inexpensive sensors. It assists in the monitoring of critical fluids such as glucose in blood. 

o Implantable Heart Sensors: By Washington University – The researchers of the university have developed customized implantable heart sensors, which assists in treatment and predictions of various cardiac disorders. The prototypes of implantable heart sensors are developed through inexpensive 3D printers.
