Introduction to Sensors in wearable devices.
Objective: To know the basic principles and applications of the sensors commonly used in wearable devices.
This short course provides an introduction to the sensors and the world of wearables, focusing on various aspects of sensor technology, ranging from bio and chemical sensors, physiological monitoring, inertial, to heat-flow and optical sensors. A range of sampling techniques and methods of chemical sensing are presented along with integration issues and the main application areas. The combination of wearable inertial sensors as accelerometers and gyroscopic sensors is discussed for evaluating motion and physical activities associated with daily living.
Since the introduction of portable devices, heart rate (HR) monitors have been extensively used in clinical practices as well as to analyze the response of the body to exercise or training stress, with an explosion during the last decade. Part of this course will be focused on the photoplethysmographic technique for heart rate monitoring.
A 3-hour hands-on activity will illustrate the HR monitoring by using a common smartphone video camera as a sensor and MATLAB for processing. A useful methodology to simulate sensors by using Multisim will be also addressed as another 3-hour practical activity.
