Tarilian Laser Technologies, a Hertfordshire, UK firm claims it has developed the “greatest technological advance in blood pressure measurement for 130 years” Unlike direct pressure measurement that every other BP meter does, the company’s Sapphire device uses an optical sensor to continuously measure blood pressure at the wrist. Keeping the Sapphire stationary will provide beat-to-beat readings and Tarilian says the device can effectively be used to detect white coat hypertension (raised blood pressure due to patient being in a clinical setting).
The company believes this technology can be translated for non-contact measurement of intraocular pressure, fetal heart monitoring, and for blood pressure monitoring using small mobile devices at different spots on the body.
