Basics and Descriptions of Different Biomedical Signals

Abstract

In the current digital era, many sensor-based devices and application are used for better life. Sensors, which are embedded in touchscreens and touchpads, are tactile in nature. These sensors acquire data from the environment that are converted into an electrical signal for further processing in the sensor system. The main aim of sensors is to estimate a specific quantity and generate a signal for interpretation. The human body constantly conveys health information that reflects the condition of organs and general health information. Such health information is typically collected by physical devices that measure different types of information such as blood sugar levels, blood pressure, heart rate, nerve condition, and brain activity. Doctors use these measurements to make diagnostic and treatment decisions. Engineers are implementing new acquisition devices that noninvasively measure different types of signals for further analysis using mathematical algorithms and formulae to develop models. This chapter includes the basics and description of different biomedical signals.
