Wearable health tech use is set to grow at an unprecedented pace worldwide, according to a new study published in the journal Nature. Researchers estimate that global consumption of wearable healthcare devices will increase 42-fold by 2050, reaching close to two billion units every year.
The study highlights how wearable health tech use is expanding as demand rises for continuous health monitoring. Devices such as non-invasive glucose monitors, ECG trackers, blood pressure monitors, and ultrasound patches now play a growing role in preventive healthcare. In fact, researchers believe non-invasive glucose monitors alone could outsell smartphones by mid-century.
To understand the environmental impact, researchers from Cornell University and the University of Chicago conducted a detailed life-cycle assessment. They studied four commonly used devices, covering raw material extraction, manufacturing, usage, and disposal. Each device can emit between 1.1 and 6.1 kilograms of carbon dioxide over its lifetime.
Moreover, the study warns that large-scale adoption will increase greenhouse gas emissions, electronic waste, and ecotoxicity risks. By 2050, China may generate the highest emissions from wearable healthcare electronics. India is likely to rank second due to rapid market growth and population size.
However, the researchers also identified practical solutions. Recyclable and biodegradable plastics offer limited benefits. In contrast, replacing critical metals and redesigning circuits can significantly reduce emissions. These changes do not affect device performance.
The study also forecasts a shift in market dominance. Initially, ECG and blood pressure monitors lead sales. By 2050, continuous glucose monitors may account for nearly 72% of all wearable healthcare devices sold.
Finally, the researchers stressed that responsible innovation can balance healthcare benefits with environmental protection. They said their framework can help manufacturers design sustainable next-generation wearable technologies.
