	== ~~Bulletpoints~~ ==		== Possible advanced extended functionalities ==

			* Isotropic or custom tailored [[elasticity emulation]] internally using chemospring designs.
			* Chemosprings with controllable lock and release functionalities
			* Combinations with [[muscle motors]] electromechanically or chemomechanically driven.

			== Why not using elastomers as springs ==

			* Hanleable energy and power density is probably lower.
			* Singly linked polymers are much more susceptible to radiation damage
			* Singly linked polymers are more susceptible to thermal damage.

	* Packaged in [[microcomponent]]s?		Inclusion of fragile polymer chains may drag the whole systems maximal operation temperature down.
	* Reason for refrainment from using elastomers: [[Consistent design for external limiting factors]]		See: [[Consistent design for external limiting factors]]
	* Macroscale crash shock absorption: what normally goes into plastic deformation heat (picture crushed metal in a car crash test) goes into cool (reversible) bond breaking.
	* More complex direction independent (anisotropic) design in [[Elasticity emulation]].
	* controllable lock and release
