Smart card allows users to securely store and access data and applications, and enables secure data exchanges. This technology provides high levels of security and privacy protection, which is an important aspect for exchanges of sensitive information (identity and personal health information, for example).
A smart sensor can be defined as a device that measures the environment, converts the input into a signal, and interfaces with a well-programmed controller. The controller then automatically calculates and delivers a control signal to an actuator that determines a quantity of output from the actuator. If the actuator is commanded to maintain physiologic homeostasis, then the system is known as a closed-loop system.
