Research unveils capabilities of Smart lens system for health and Well-being


In the last calendar year, the COVID-19 pandemic has had an enormous impact on world communities in more than one way. And, other diseases have had impact too. This prompted medical researchers for the development and application of medical devices and bioelectronics to monitor and diagnose health status in real-time.

In fact, among all devices, smart contact lenses attract extensive interests. This is due to their capability to directly monitor ambient and physiological information. Coming to their capability, smart contact lenses fitted with high sensitivity responsiveness would open the feasibility if non-invasive method could be used to continuously discover biomarkers in tears. In addition, smart contact lenses could also be fitted with circuit chips that are application specific. This would further enrich the functionality of smart sensors to obtain, process, and transport physiological properties, oversee illnesses and health risks, and assist health and well-being.

Nonetheless, multistep integration processes are still required for previous demonstrations of smart contact lenses.

New Contact lens Sensor system offers two advantages

Meanwhile, researchers at a few academic and research institutions have developed an ultrathin contact lens sensor system with multifunctionality. This includes a sensor system with a photodetector for receiving optical information, temperature sensor to diagnose potential corneal disease, assistance for imaging and vision, and a glucose sensor to monitor glucose level directly from tears.

“With the development of the lens sensor system, it provides two advantages. First, it provides a new and easy method for the manufacture of advanced smart contact lenses, and new insights for the design of other multifunctional electronics for human machine interface,” said the lead researcher.

In fact, the ultrathin serpentine mesh sensor system based on transistors allow to incorporate other functional components.
