The Aktiia bracelet indirectly estimates blood pressure changes through optical signal processing. In order to provide absolute values of blood pressure in units of mmHg, an initialization with a reference value is needed. The reference measurement has to be taken with the initialization cuff, which is a validated sphygmomanometer device like most standard blood pressure cuffs.

Aktiia Bracelet G1 has been validated in multiple clinical trials according to ISO-81060-2 standards and has received the CE marking as a Class IIa medical device. For additional information please refer to the evidence section on our website.
