Prognosis and diagnosis of any disease as well as its subsequent management has become quite easy now, with the advent in bioinstrumentation, more specifically with biosensors. Just as environmentalists can predict the level of pollution by analyzing the population of butterflies or the color of moths, a ‘biosensor’ is a device that detects our body’s physiological activity to send signals and analyze health-related conditions for diagnosis and/or subsequent treatment.
Everyone is rushing around in today’s fast world, and as a result of this daily pace, diseases are also becoming more prevalent. The lack of clinical resources has led to significant demand for wearable and portable healthcare devices as a potential solution.
Biosensors have become extremely popular today because they support the method of non-invasive monitoring – that is, a monitoring procedure that does not involve any surgical intervention in the body (Read more about the basics of biosensors).
These wearable sensors can be in the form of smartwatches, smart shoes, contact lenses, earpieces, and mouthpieces depending on the location of the body. The technology provides a wireless mechanism that makes it easier for patients to use. Skin is the outermost layer of our body and along with the protection, it also provides a lot of information about the physiological activity of the body through sweat and wound exudates. With the help of wristbands, patches, and smartwatches, the important details in case of hyperglycemia or hypertension can be measured to get instant treatment. Contact lenses can give information about changes in pH levels of the tears. Mouthpieces can be used to detect the rate of saliva production, which is known to be altered in response to exercise, stress, and dietary intake.
Today it might be difficult for people living in remote locations to have close access to any health center but devices such as these would help them get one step closer towards early detection and treatment.
Indeed, when it comes to biosensors, the future is already here.
