Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. An RFID system consists of a tiny radio transponder called a tag, a radio receiver , and a transmitter .
Radio frequency (RF) is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in ...
Wildlife radio telemetry has advanced the research opportunities available for studying animal populations. It can be applied to many areas of management and research to determine the habitat use of tagged animals, such as roost and foraging habitat preferences. [5] Radio telemetry has been used to study the home range and movement of populations.
Since then, photo-identification has been used to study many marine species in order to determine aspects of their biology, ecology, and behaviour. Rather than spend time compiling and analyzing the numerous photographs, computer programs have been created to help researchers identify individuals and resighting events using existing photo ...
X-ray image of a microchip implant in a cat. A microchip implant is an identifying integrated circuit placed under the skin of an animal. The chip, about the size of a large grain of rice, uses passive radio-frequency identification (RFID) technology, and is also known as a PIT (passive integrated transponder) tag.
Bioelectromagnetics, also known as bioelectromagnetism, is the study of the interaction between electromagnetic fields and biological entities. Areas of study include electromagnetic fields produced by living cells, tissues or organisms, the effects of man-made sources of electromagnetic fields like mobile phones, and the application of electromagnetic radiation toward therapies for the ...
Radio fingerprinting is commonly used by cellular operators to prevent cloning of cell phones — a cloned device will have the same numeric equipment identity but a different radio fingerprint. Essentially, each transmitter (cell phones are just one type of radio transmitter) has a rise time signature when first keyed which is caused by the ...
