The Future of Wearable Technology in Healthcare

Wearable devices are becoming more impactful in the healthcare industry today. People want to obtain higher access to professional devices outside healthcare institutions and have the possibility to monitor their health on their own. That’s why healthcare technology started extending beyond the borders of hospitals, rehabilitation facilities, clinics, and others in the form of wearables. Now, they are more accessible in the mass market and people can afford to have personalized healthcare devices in their homes.

With the Coronavirus outbreak and the rise of telehealth and telemedicine from 19.5% to 61.05% between 2020 and 2021 in the USA alone, the demand for wearable devices has also grown. According to an IDC survey, despite the supply chain constraints, wearables shipments increased by 9.9% in Q3 of 2021, reaching 138.4 million units.

In this article, we’ll look into how wearable health tech is utilized in healthcare and what the future of wearable technology is like in healthcare.

Wearable Gadgets for Smart Healthcare

There is a wide variety of wearable healthcare gadgets in the market and many more are being developed. Let’s have a look at some of the devices available today.

• Fitness trackers 

Fitness trackers are the most widespread type of smart healthcare wearable gadgets used en masse. Sportspeople, healthy lifestyle followers, and health influencers use fitness trackers to monitor their daily physical activity and gain insights into their health and wellness. The most common parameters measured with fitness trackers are: number of steps, sleep stages, heart rate, pulse, number of burnt calories.

• Smartwatches

Smartwatches are updated fitness trackers with wider functionality. While fitness trackers come in the form of a band and are used just for monitoring activity, smartwatches look like electronic watches with wider screens connected to smartphones. Apart from activity tracking, smartwatches can also deliver notifications, emails, and messages from social media.

• Electrocardiogram monitors

Electrocardiogram monitors (ECG/EKG) are devices that measure how well a patient’s heart is working and they have recently appeared in the wearable gadget market.

For now, wearable ECG gadgets use only a single-lead probe which is much fewer than twelve leads in ECGs utilized in hospitals. Though the technology is less effective than hospital appliances, it still can help to detect some heart problems such as arrhythmias, atrial fibrillation, and others. Many smartphone and gadget manufacturing companies have already updated their smartwatches with ECG monitors, including Apple Watch, Samsung Galaxy, Fitbit Sense, Amazfit, and others.

• Blood pressure monitors

Blood pressure monitors are another recently developed wearable smart devices that are quickly becoming popular. This type of monitor doesn’t require an inflatable cuff applied to the user’s wrist or upper arm, instead, they use some other biological data e.g. pulse transmit time or optical sensors to estimate blood pressure. The technology is still developing and improving. Samsung, BioBeat, and Heartisans are actively experimenting with wearable blood pressure monitors.

• Biosensors

Wearable biosensors are currently under development portable electronic devices. They can be integrated with or into the human body, e.g. tattoos, gloves, clothing, or implants synced with mobile phones or other gadgets. The market doesn’t offer biosensors for mass use yet, but they have the potential to revolutionize the healthcare and telemedicine realms.

Wearable Technology in Healthcare: Examples and Use Cases

Wearable technology helps to enhance healthcare, facilitating the industry for patients and doctors. Doctors can make precise diagnoses, gaining more and real-time information about their patients, whereas patients don’t have to necessarily visit hospitals to get diagnosed.

Here is how wearable technology can be used in healthcare today:

• tracking health status – with health monitoring devices doctors can track and measure their patients’ vitals in real-time such as heart rate, blood pressure, body temperature, etc.; the gadgets can transmit the necessary patients’ data to the doctors for further examination;
• therapeutic treatment – patients with chronic diseases can get timely treatment once their metrics exceed the level, e.g. getting automated insulin pumps or medications; moreover, with these devices, doctors can better adjust the patients’ therapy through monitoring their patients’ conditions;
• activity tracking – apart from doctors monitoring their patients’ state, wearable gadget users can track their health status on their own; in case of any irregularities, they can seek consultation from a qualified doctor to take preventative action to any disease development.
