A solar-powered device to measure blood pressure can provide affordable and reliable testing in low-income countries, according to a research published in Hypertension: Journal of the American Heart Association.

The World Health Organization had asked several companies to develop solar-powered blood pressure monitoring devices that would be accurate and easy to use, and one device was selected after evaluation.

The solar device was found to be 94% in agreement with the standard blood pressure testing method for systolic blood pressure.

A study conducted in Uganda and Zambia saw trained staff use the new device and a standard device on 716 participants.

The study results showed that both the patients and healthcare professionals preferred the new device due to its automated features and ease of use.
