Sky Labs moves to develop a calibration-free blood pressure ring ... secures clinical data

[Financial News] Sky Labs is moving to develop a next-generation ring-type blood pressure monitor that eliminates the need for individual calibration each time blood pressure is measured. The company plans to refine its measurement technology using clinical experience and real-world data accumulated in medical settings, and to establish evidence that can be used to manage blood pressure and guide treatment decisions.
Sky Labs said on the 21st that it had presented clinical use cases for its ring-type blood pressure monitor, CART, and the development direction for calibration-free blood pressure measurement technology at the 70th Korean Society of Cardiology Autumn Scientific Conference (KSC 2026), held at Grand Walkerhill Seoul from the 15th to the 17th.
At the conference, Sky Labs CEO Lee Byung-hwan explained that the company is developing technology to measure blood pressure without separate calibration, using real-world data, and is pursuing commercialization. Existing blood pressure monitors may use a cuff that compresses the arm, or may require calibration to ensure accuracy even when measuring without a cuff. Sky Labs is developing technology that reduces this burden and can be used for continuous blood pressure management.
The potential for use in medical settings was also discussed. Lee Hae-young, a professor in the Department of Cardiology at Seoul National University Hospital, explained that the CART blood pressure monitor is being used in clinical settings to supplement or replace conventional cuff-based monitors. The professor said it could help identify white-coat hypertension, in which blood pressure is elevated only in the clinic; masked hypertension, in which readings are normal at the clinic but blood pressure rises in daily life; and variable blood pressure, which fluctuates considerably over time, helping guide treatment decisions.
A research plan to verify the clinical usefulness of cuffless blood pressure measurement was also unveiled. The CUFFLESS Study, a project marking the 30th anniversary of the Korean Society of Hypertension, will follow for four years one group of patients treated based on their clinic blood pressure and another treated based on 24-hour ambulatory blood pressure measured with the CART monitor, and compare the incidence of cardiovascular and cerebrovascular diseases. The study will assess how differences in measurement methods affect actual treatment outcomes.
The conference also presented nighttime blood pressure measurement results and cases of using the CART blood pressure monitor with patients with atrial fibrillation and heart failure.
Lee said, “The competitiveness of cuffless blood pressure monitors lies not only in how convenient they are to use, but also in how much useful information they provide in actual clinical practice,” adding, “We will refine our calibration-free technology based on clinical evidence and real-world data, and expand its applications in global markets.”
