A polymer gel is crosslinked polymer network swollen in solvent. Some gels undergo abrupt volume changes by swelling–shrinking in response to external stimuli, such as temperature or electric field. Recently a new type of biometric gel has been developed which autonomously repeats its swelling‐shrinking cycles periodically in a closed solution, without any external stimuli, similar to a beating heart muscle. The new materials and their rhythmical behavior are discussed.
