The most critical aspect of the design of a photoelectrochemical device for water splitting is the choice of suitable photoanode and/or photocathode materials. Several of the requirements imposed on these materials appear to be in conflict, and certain trade-offs have to be made. In some cases, these trade-offs can be avoided by adopting smart architectures and materials combinations. The remainder of this chapter gives a few general considerations and approaches more detailed accounts of strategies to cope with these trade-offs are given in later chapters. 

The latest embodiment of an SMP clot retrieval system demonstrates a hybrid shape-memory material system. The design of SMP biomedical devices should not be limited to purely polymer-based devices but rather can be combined with other smart or active materials. Novel multifunctional SMP-hybrid systems could lead to multiple unique and novel platform technologies for future development. 

Piezoelectric polymers have been known for more than 40 years, but in recent years they have gained repute as a valuable class of smart materials. There is no standard definition for smart materials, and terms such as intelligent materials, smart materials, adaptive materials, active devices, and smart systems are often used interchangeably. The term smart material generally designates a material that changes one or more of its properties in response to an external stimulus.

The smart materials /stmctures field is new. As these materials are better understood, better devices can designed with them and the quaHty of life may be enhanced. 

The design of shape-memory devices is quite different from that of conventional alloys. These materials are nonlinear, have properties that are very temperature-dependent, including an elastic modulus that not only increases with increasing temperature, but can change by a large factor over a small temperature span. This difficulty in design has been addressed as a result of the demands made in the design of compHcated smart and adaptive stmctures. Informative references on all aspects of SMAs are available (7—9). 

The field of materials chemistry and nanoscience builds the bridge between fundamental chemistry and applied science and technology. The synthesis of materials, the improvement of their physicochemical properties, the development of reliable processing and fabrication routes leading to miniaturization, and the design of smart structures and devices are pivotal to industrial growth and a competitive economy.
