Abstract
The present disclosure provides a polymer-based turgor actuator including a polymer network member (hereinafter, polymer member) capable of absorbing liquid and swelling, and a permeable confinement member configured to physically constrain the polymer member by confining it in an internal accommodation space and having liquid permeability, wherein an acceptable volume of the internal accommodation space of the permeable confinement member is smaller than the maximum swelling volume of the polymer member in the absence of the permeable confinement member.
