Ultra-compact blood-flow sensor can be worn to keep track of things

A research group from Universities in Tokyo and Kyushu has created an extremely small, wearable device that is capable of sensing the flow of blood in the body. Size is not a hindrance for the world’s first wearable sensor that can measure the flow of blood even when a person is on the move. Blood flow sensors used until now weighed almost 3 kg and needed a continuous power supply of 100 V. This ingenious device supersedes all previous blood flow sensors since it is wireless, small in size, and requires less power.

Blood-Flow Sensor

Real time measurement of blood flow can prove to be of immense help in safeguarding a person‘s health. A person who is running can be warned by the device when a dehydration condition is approaching. Created with the advanced MEMS technology, this minute device can also act as a preventative medicine by detecting the level of alcohol in blood. Blood pressure can also be checked with the help of this sensor.

Researchers are working on reducing the sensor’s size even further so that it can be easily strapped on to one’s ear, arm, forehead or even finger for data collection. Such a device with multiple benefits can prove to be a breakthrough in different fields. It is a matter of great relief for patients to be aware of the fact that their blood pressure is constantly being monitored even when they go about their daily routine.

Research scientists have created a prototype of this device for chickens. When chickens contract bird flu, it slows down their blood circulation. It is difficult to take a blood sample in this situation as the flow of blood in chickens becomes extremely sluggish. The sensor helps prevent this situation by detecting bird flu at an early stage. It can also be used to check the health of cattle which are used for the production of essential food items. For example, industries in Japan can use it to monitor reproductive cycles of cattle to ensure superior quality of beef during mass production. The blood flow sensor can also monitor the health of cows during the various stages of their pregnancy, up to the time they are ready for reproduction.

This simple easy to use device is still being tested out by the researchers so that there is enough data to justify its benefits. After obtaining sufficient test results, the blood flow sensor will be introduced in the market where Japanese businesses will definitely grab it.
