Application of various kinds of Sensors in the Healthcare Segment

Published Date : July 10, 2017

Introduction

Sensors are gadgets that identify and recognise any physical, chemical or biological indications and give a path to those signs and data to be properly measured and recorded. Physical phenomenon that can be detected includepressure, temperature, vibration, level of sound, intensity of light, rate of flow of gasses and fluids, intensityof electric and magnetic fields, and concentration of numerous substances in vaporous, fluid, or solid shape.

Sensors in medical field can be used in many forms for example as a glucose sensor that resembles a watch that when placed on the skin, delivers little electric charges, to open up pores so sample can be separated to read the blood sugar readings or a sensor to distinguish pathogens by a biosensor, which utilizes incorporated optics and immunoassay methods. Changes in the emission of the laser light by the sensor show the presence of particular microscopic organisms.

Market for Medical Sensors

The global market for Interventional Cardiology and Peripheral Vascular devices was evaluated at USD 9.4 billion in 2015 and is expected to grow to USD 15.01 Billion by 2022, rising rapidly at a CAGR of 8.5% for the next five years. The market driving factors in this case are the increasing geriatric population worldwide, large number of applications in various analysis procedures and people preferring home healthcare services over treatment in hospitals due to increasing costs of medicinal services. Apart from these the market demand for sensors is fuelled due to decreasing prices, miniaturization, increasing health and fitness awareness among younger generation and the smartphone technology. On the other hand the market demand is hampered by factors such as privacy concerns, lack of safety standards and inability of some people to pay for even the cheapest of such devices.

Applications of Medical Sensors

  • Monitoring the Health: They can collect and store various crucial data about the physiological health of a person with even chronic conditions. Some fitness sensors are even preferred by some athletes or even enthusiastic fans being very health conscious.
  • Monitoring of Safety: Many sensors can detect accidents, seizures of epilepsy and even heart attacks. They can detect these events as they are happening and then alarm the concerned relatives and can call for medical help.
  • Home Rehabilitation: It can be used to provide virtual reality environments and give home based physiotherapy.
  • Treatment Efficacy: They can track any physiological changes as well as chronic conditions on a regular basis.
  • Early detection of diseases: They can detect diseases and any harmful signs of changes in a patient’s physiology which leads to timely treatment and cure.
