Blood Flow Sensor

Cc0 public domain a study led by researchers at ucl has.

Blood flow sensor.

The sensor detailed in a paper published jan. 8 in nature biomedical engineering monitors the flow of blood through an artery. Furthermore it could eliminate costly monitoring tests decrease frequent subjective human evaluations and limit time consuming clinic visits. Because it is biodegradable battery free and wireless.

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. It does not need to be removed. The sensor would help surgeons to monitor blood flow across vascular anastomoses continuously after surgery. But an experimental sensor that clings to skin like a temporary tattoo could enable 24 hour monitoring of blood flow wherever a patient goes.

Measurement of blood flow is critical in many medical specialties so a wireless biodegradable sensor could impact multiple fields including. Blood flow measurements were taken as the human. By university college london. The sensor monitors the flow of blood through an artery and can warn a patient s doctor if there is a blockage.
