Blood Flow Sensor

Furthermore it could eliminate costly monitoring tests decrease frequent subjective human evaluations and limit time consuming clinic visits.

Blood flow sensor.

The sensor monitors the flow of blood through an artery and can warn a patient s doctor if there is a blockage. Early detection of decreased blood flow would lead to less morbidity. It is biodegradable battery free and wireless so it is compact. Devices equipped with this new sensor will be able to measure blood flow volume in subcutaneous tissue by placing the device in contact with an ear finger or forehead 2 when light is reflected on blood within a blood vessel the frequency of light varies called a frequency or doppler shift according to the blood flow velocity.

The sensor detailed in a paper published jan. Blood flow measurements were taken as the human. The sensor would help surgeons to monitor blood flow across vascular anastomoses continuously after surgery. Brain blood flow sensor discovery could aid treatments for high blood pressure and dementia.

But an experimental sensor that clings to skin like a temporary tattoo could enable 24 hour monitoring of blood flow wherever a patient goes. Cc0 public domain a study led by researchers at ucl has. Because it is biodegradable battery free and wireless. It does not need to be removed.
