1 General Introduction: Smart Materials, Sensors, and Actuators

The early twenty‐first century has foreseen acceleration of innovations in robotics and automations as well as artificial intelligence (AI), where sensors/transducers and smart materials play very important roles. The concept of AI has been around since the late 1950s; however, it's only since the first decade of the twenty‐first century that excitement about it has really begun to grow due to the ability of fast computation and abundant size of memory devices. A very successful demonstration of AI is Google's AlphaGo, which is the first computer program to defeat a professional human Go player (see Figure 1.1). Another successful application of AI is the unmanned vehicles and aircrafts where large number of sensors and actuators are used.
