- Smart Materials: Pioneers of Adaptive Functionality
Smart materials are a cornerstone of SMASIS, defined by their ability to respond adaptively to external stimuli, such as temperature, pressure, humidity, and electric or magnetic fields. These materials can undergo significant changes in their physical properties, such as shape, stiffness, or color, based on the nature and intensity of the stimuli.
1.1 Shape Memory Alloys (SMAs): SMAs are one of the most well-known types of smart materials, capable of “remembering” and recovering their original shape after deformation. They find applications in medical devices, aerospace components, and robotics.
1.2 Piezoelectric Materials: These materials generate an electric charge when subjected to mechanical stress and, conversely, deform when an electric field is applied. Piezoelectric materials are essential in sensors, actuators, and energy harvesting devices.
1.3 Electroactive Polymers (EAPs): EAPs change shape or size in response to an electric field, offering versatility in applications such as artificial muscles, haptic feedback, and soft robotics.
- Adaptive Structures: The Art of Responding to Change
Adaptive structures refer to systems that can change their shape or behavior in response to external stimuli or varying environmental conditions. The integration of smart materials into the design of structures enables them to adapt dynamically, enhancing performance, efficiency, and safety.
