v. t. e. The antennas contained in mobile phones, including smartphones, emit radiofrequency (RF) radiation (non-ionizing "radio waves" such as microwaves); the parts of the head or body nearest to the antenna can absorb this energy and convert it to heat. Since at least the 1990s, scientists have researched whether the now-ubiquitous radiation ...
Some of the first uses of biotelemetry systems date to the early space race, where physiological signals obtained from animals or human passengers were transmitted back to Earth for analysis (the name of the medical device manufacturer Spacelabs Healthcare is a reflection of their start in 1958 developing biotelemetry systems for the early U.S. space program).
Molecular communication. Molecular communications systems use the presence or absence of a selected type of molecule to digitally encode messages. [1] The molecules are delivered into communications media such as air and water for transmission. The technique also is not subject to the requirement of using antennas that are sized to a specific ...
Wireless communication (or just wireless, when the context allows) is the transfer of information (telecommunication) between two or more points without the use of an electrical conductor, optical fiber or other continuous guided medium for the transfer. The most common wireless technologies use radio waves. With radio waves, intended distances ...
Hemodialysis, a process of purifying the blood of a person whose kidneys are not working normally. Biomedical engineering (BME) or medical engineering is the application of engineering principles and design concepts to medicine and biology for healthcare applications (e.g., diagnostic or therapeutic purposes).
This notebook computer is connected to a wireless access point using a PC Card wireless card. An example of a Wi-Fi network. A wireless LAN (WLAN) is a wireless computer network that links two or more devices using wireless communication to form a local area network (LAN) within a limited area such as a home, school, computer laboratory, campus, or office building.
Biosensor. A biosensor is an analytical device, used for the detection of a chemical substance, that combines a biological component with a physicochemical detector. [1][2][3][4] The sensitive biological element, e.g. tissue, microorganisms, organelles, cell receptors, enzymes, antibodies, nucleic acids, etc., is a biologically derived material ...
A wireless network is a computer network that uses wireless data connections between network nodes. [ 1 ] Wireless networking allows homes, telecommunications networks and business installations to avoid the costly process of introducing cables into a building, or as a connection between various equipment locations.
