Fitness Trackers

A fitness tracker allows you to trace a number of variables such as the steps you walk in a day, your blood pressure, the number of hours you sleep and even the quality of your sleep. They also can be plugged in to a computer or your smartphone to generate a number of statistics based on the recorded data.

In the 1960s the Japanese came up with the first fitness tracker which could count your daily steps. It was worn around the waist and that’s when the concept of walking ten thousand steps a day to stay fit began. As the technology improved more variations of the fitness tracker came up and now we can wear one on the wrist.

The wrist worn fitness trackers have been popular for the last decade and use sensors to track various different human body parameters. They can tell us how many calories we need to burn to lose weight and can even keep track of the number of calories we have consumed.

If you are not keen on the wrist worn fitness tracker, the latest generation of trackers can literally be popped into your ear. The earbuds can monitor your heart rate, speed and mileage with ease. Now this is one science project keen on miniaturization.
