Wearable biosensors are bringing this vision to life! They are mini devices that continuously monitor your vital health metrics like heart rate, blood pressure, and glucose levels. Seamless real-time data integration and actionable healthcare insights help users of wearable biosensors take charge of their well-being and equip healthcare providers with tools for preventative care. Stay with us till the end to learn about wearable biosensors, examples of how they work, and their benefits in detail!

What Are Wearable Biosensors?

Wearable biosensors are compact and usually noninvasive devices designed to monitor and measure biological and physiological parameters in real-time, such as blood sugar levels and heart rate. Typically, they are worn on the body, such as on the wrist, arm, or chest, to continuously track vital signs. This provides valuable real-time data that can be analyzed to identify potential health concerns and initiate preventive care. 

Wearable biosensors have three important components that help monitor and analyze health metrics: 

• The recognition region helps detect the target signal. 
• A transducer converts that signal into a measurable parameter.
• An electronic processor for a visual interface to project results. 

The recognition region of wearable biosensors detects the target signal, such as a biomarker or physiological parameter, specific to the user’s health. This signal is then passed to the transducer, which converts it into a measurable value, often as an electrical signal. Finally, the electronic processor transforms this signal and displays the results on a connected device, allowing users to monitor their health in real-time and make informed decisions.

Challenges and Future of Wearable Biosensors

Some common challenges in the adoption or usage of wearable biosensors include: 

Stability of Wearable Biosensors

Wearable biosensors, particularly enzymatic sensors, have significant stability issues due to environmental factors like temperature, humidity, and exposure to air. Enzymes in these medical biosensors degrade rapidly, becoming less functional and accurate with time. For example, factors like sweat pH variations or temperature fluctuations denature enzymes, impairing their catalytic activity and ultimately reducing overall sensor performance. Other than that, mechanical stress from skin movement can further compromise its stability and reliability.

Solution: Researchers are actively developing protective coatings, such as advanced nanomaterials and flexible substrates, that can enhance the stability of wearable biosensors. These coatings can shield enzymes from harsh external conditions while maintaining their activity. Moreover, designs incorporating multilayer structures can help keep enzymes in the wearable sensors away from direct contact with sweat, reducing the risk of degradation. These advancements increase the optimal long-term usability and reliability of wearable biosensors in real-world applications.
