7. ADVANTAGES OF SMART
MATERIAL
 Smart materials can adapt their properties automatically in response to environmental
changes, improving system performance and efficiency.
 They offer multifunctional capabilities, such as self-healing, shape changing, or
sensing, which traditional materials cannot provide.
 Many smart materials enable systems to operate more efficiently by reducing the need
for external energy inputs or active controls.
 Smart materials can detect damage or changes in their environment.
 Some smart materials contribute to sustainability by improving energy efficiency and
reducing waste through longer product life cycles.

8. DISADVANTAGES OF SMART
MATERIAL
• Smart materials are often expensive to develop and manufacture due to complex
processes and specialized raw materials.
• Some smart materials degrade or lose functionality after repeated use or exposure
to harsh environmental conditions.
• Certain smart materials require continuous energy input or high power to maintain
their active state, limiting their use in low-power applications.
• Some smart materials do not respond quickly enough for real-time applications,
reducing their effectiveness in dynamic environments.
• Some smart materials may involve toxic or non-biodegradable components, raising
environmental and health risks.
