Blood flow sensor.

Blood flow measurements were taken as the human. The sensor detailed in a paper published jan. Cc0 public domain a study led by researchers at ucl has. Measurement of blood flow is critical in many medical specialties so a wireless biodegradable sensor could impact multiple fields including.

But an experimental sensor that clings to skin like a temporary tattoo could enable 24 hour monitoring of blood flow wherever a patient goes. It does not need to be removed. Furthermore it could eliminate costly monitoring tests decrease frequent subjective human evaluations and limit time consuming clinic visits. The sensor monitors the flow of blood through an artery and can warn a patient s doctor if there is a blockage.

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. Brain blood flow sensor discovery could aid treatments for high blood pressure and dementia. Because it is biodegradable battery free and wireless.
