Previous sensors weighed up to 13 pounds.

Japanese researchers have invented a pretty nifty device: an ultra-compact blood flow sensor. According to the inventors from Kyushu and Tokyo Universities, the device is “the world’s first blood flow sensor that can take measurements while you move. Until now, blood flow sensors weighed 2-3 kg, and they needed a 100 V power supply. We’ve made a wireless, ultra-compact, low-power version.”

Apparently, the sensor can detect real-time dehydration in a runner.

It can be also used for health monitoring, preventative medicine, and alcohol monitoring.

The new sensor is expected to get smaller. Already a prototype is in use in chickens. According to the researchers: “When chickens get bird flu, their blood flow slows down,”Their circulation gets so sluggish, it makes taking blood samples difficult.”

The researchers hope to get the sensor down to the size that it will fit in the ear or can be worn on the finger. The device also measures blood pressure. One question left unanswered in the article: Can it detect blood doping?
