Magnetic earring heart rate sensor.

Intelligent design of sensor attachment and the use of advanced signal-processing methods are required for the development of wearable biosensors capable of providing accurate measurement during daily activities. This miniaturized earring sensor can be worn comfortably on the earlobe and contains an embedded accelerometer to provide a motion reference for adaptive noise cancellation. Performance of the sensor was evaluated for three common physical activities, including standing, walking and running.
