Abstract
This application discloses a potable, easy-to-use miniature cardiovascular sensor that is capable of monitoring heart rate, blood flow and blood pressure 24/7, using optical non-invasive method. It utilizes interferometric detection to improve signal to noise ratio. It also utilizes phase controlled focusing beam to reduce the optical power needed and therefore minimizing the power consumption, making it practical for continuous monitoring. The integrated optical chip assembly shrinks the total sensor size and makes it suitable for wearable devices, hence, this device will be portable and removable.
