Dielectric Electric Active Polymers (DEAP) has shown great potential as actuator materials.
Introduction Dielectric Electro Active Polymers are new category materials.
The DEAP materials for energy scavenging allow large mechanical deformation combined with low operating forces and a very energy density.
The low cost of DEAP materials is promising for their applications, but more development of DEAP electronics is needed before we know how they will compare to competitive approaches in smaller, cost-sensitive applications.
