Pedometer is usually worn on the belt and kept all over the day. Its name is suggestive enough that it measures how many steps you take during the day. Pedometer is portable and electromechanical or electronic. It does its work by finding out the motion of the wearer’s hips. Originally meant for sportspersons, it has now become popular as everyday exercise calculator and motivator. It records how many steps the user has walked in a day and thereby the kilometers or miles (Distance = Number of steps x Step length). Nowadays, pedometers are integrated in consumer electronic devices, like mobile phones and music players.


Accelerometer is basically a device to measure acceleration in anything, like vehicles, animals, machines or winds, and it can also be designed to measure physical activity. Technological advances have made it possible to wear minimally intrusive accelerometers to measure physical activity. There are different types of them, like piezoresistive, piezoelectric crystals and electronic piezoelectric sensors, most of which use some or the other spring mass system. The acceleration recorded is proportional to muscular forces and thus it can be translated in energy expenditure.
