Highlights of Recent Achievements

Prof. Zhao’s team has achieved the first epidermal (i.e., skin-like) optoelectronic sensor for low-power and continuous tracking of arterial blood pressure (BP).

Prof. Zhao’s team has developed the material solutions to address the processability and operational stability issues of perovskite solar cells and LEDs. Their pioneering work in composition tuning, precursor engineering and surface passivation has led to multiple “Highly Cited Papers” rated by Web of Science.

Prof. Zhao’s team has developed a multi-wavelength photoplethysmogram (MWPPG) model, which led to a new record in cuffless BP measurements for its lowest measurement error (< 2.5 mm Hg) and enabled simultaneous acquisition of heart rate, BP, respiratory rate and blood oxygen level with just one integrated optical module.
