In some implementations, the strength of the excitation signal may be determined based on, for example, wave length, wave speed, wave frequency, historical values, sensor data wherein the sensors may track factors such as stress or displacement, and/or the like. There are also devices developed to harness the power of moving fluid, whereby an electromagnetic generator is coupled to the fluid, such as by a turbine wheel, to produce electrical energy for distribution and consumption by all manner of electrical-energy-powered devices. Some of the propulsion and generator embodiments disclosed thus far have utilized rotary reciprocating motion of the vertebral plates, with the CS fins 5 coupled to the vertebra plates 4 so that the CS fins 5 undulate substantially in-phase with each other FIG 41. The longitudinal strips 20 also undulate substantially in-phase with each other in such embodiments. For generator embodiments of the invention, forces 14 from ambient moving fluid may cause the deformations of the CS fins 5 to shift in position, imparting force onto the tendons 7. This force on the tendons 7 may cause them to lengthen or shorten in some implementations.
For propulsion embodiments, when the elastic or variable coupling components are actuated with an input of energy, such as an excitation, they will change length and impart forces onto the deformed, flexible sheet-like members, causing their deformations to shift position. Rotation of the vertebra plates causes the lengths of the tendons 7 to change. The longitudinal strips 20 are unable to return to their pre-deformed shape after being restrained via attachment to the vertebra plates 4. Therefore, undulations in the longitudinal strips 20 persist and undulations, such as traveling undulations, are expressed as partial rotation of the vertebra plates 4 clockwise and counterclockwise. FIGs 29-33 illustrate aspects of a vertebra plate 4 undergoing a sequence of clockwise rotations and show how the tendons 7 change length with rotation in one implementation. FIG 45 illustrates some aspects of a bilateral reciprocating embodiment with its longitudinal strips 20 removed. In one embodiment the restraining components are vertebra plates to which the deformed, flexible sheet-like members are attached in such a manner that they are unable to return to their relaxed state.

60. providing a second excitation to the second subset of the plurality of transducers when the condition is satisfied, wherein the second excitation disrupts the excited equilibrium state for the second subset of the plurality of transducers by allowing a second value of the restraining force to overcome a second value of the restoring force, and wherein the second value of the restraining force is different than the first value of the restraining force based on displacement of the second restraining component. BACKGROUND – Mechanical devices actuated to perform prescribed motions for a variety of purposes are ubiquitous. For actuated embodiments, actuation of the tendons 7 will cause them to lengthen or shorten, thereby changing the internal energy state of the CS fins 5 and thereby causing the position of the deformation, or deformations, to shift position. It is to be understood that while the embodiments discussed herein focus on examples utilizing electroactive polymer materials for the tendons 7, the mechanical principles brought to bear work equally well for embodiments in which the tendons 7 may be any elastic or variable length transducer.
