What is the principle behind the operation of a system that measures heart beats through the variation of blood volume?
The principle is based on the fact that blood absorbs or reflects part of the emitted light and the variation of the blood volume caused by heart beats modulates the amount of transmitted or reflected light.
What is the categorization of analyzed projects in a frequently cited survey work?
The projects are classified into (i) in-body (implantable), (ii) on-body medical, and (iii) on-body nonmedical systems.
What is the focus of the survey in Ref., regarding wearable sensor-based systems?
The focus is on the functional perspective of the analyzed systems (i.e. what kind of applications they target).
How are systems divided and grouped in Ref., in terms of hardware characteristics?
Systems are divided into commercial products and research projects, and also grouped on the basis of hardware characteristics: Wired electrode-based, smart textiles, wireless mote-based, and based on sensors found in commercial smartphones.
What is the significance of Body Sensor Networks (BSNs) in various application domains?
BSNs can play a critical role in a very wide range of application scenarios.

What is the role of signal processing in BSN systems, and how is it used in the LiveNet system?
Signal processing is an essential component of BSN systems, as it enables the extraction of meaningful information from sensor data. In the LiveNet system, signal processing is used to detect Parkinson's symptoms and epilepsy seizures.
What is the advantage of using task-oriented programming in BSN systems, and how is it used in the MyHeart system?
Task-oriented programming allows for the development of BSN systems that are focused on specific tasks or applications. In the MyHeart system, task-oriented programming is used for the prevention and detection of cardiovascular diseases.
How do autonomic systems relate to BSNs, and what is an example of an autonomic system in BSNs?
Autonomic systems are self-managing systems that can adapt to changing conditions, and BSNs can be designed to operate autonomically. An example of an autonomic system in BSNs is the Human++ system, which uses low-power BSN nodes to monitor general health.
What is the significance of BSN programming frameworks, and how are they used in the AMON system?
BSN programming frameworks provide a structured approach to developing BSN systems, and they can be used to simplify the development process. In the AMON system, a BSN programming framework is used to develop a cardiac-respiratory disease monitoring system.
