$GTCH's joint Venture GBT Tokenize Corp (“GBT/Tokenize”) is currently developing an additional feature for its qTerm device. The additional feature will be a blood pressure measurement system and it is planned to be released with the product's second release during Q1 2021.

Typical blood-pressure apparatus is built using bulky and mechanical cuff-based medical devices. qTerm is planned to introduce a solid-state based blood-pressure monitoring solution, in order to enable a more convenient measurement system that will make tracking and monitoring easier. Cardiovascular disease is a leading factor of death and disability, and elevated blood pressure is a major contributor to these types of health risks. Early detection of hypertension can alert users to follow with appropriate therapy and treatment.

GBT/Tokenize’s blood pressure solution will comprise a complete integrated optical sensor module, and an embedded microcontroller. A sensing firmware algorithm will provide the operation and control of the entire system. Such method is called photoplethysmography (PPG) and its goal is to detect blood volume changes in the microvascular tissues. qTerm users will be able to measure blood pressure simply by placing their finger on the device while resting, at any time and anywhere.
