Biochip is a collection of miniaturized test sites arranged on a solid substrate used to analyze organic molecules associated with living organisms. It was initially developed in 1983 for monitoring fisheries and saw large scale development in the 1990s. A biochip implant system has two components - a transponder implanted under the skin that contains a microchip, antenna coil, and glass capsule, and an external reader that activates the transponder and displays the ID number. Biochips have applications in tracing, storage of medical information, and identifying individuals, and can also be integrated with sensors to monitor conditions like glucose levels.
