Robots are increasingly integral across various sectors due to their efficiency and superior capabilities, which enable performance beyond human potential. However, the development of robotic systems often conflicts with sustainable goals set by United Nations, as they generate considerable nondegradable waste organic/inorganic pollutants throughout life cycle. In this paper, we introduce a dual closed-loop system that integrates biodegradable, materials such plasticized cellulose films NaCl-infused ionic conductive gelatin organogels. These undergo ecological cycle from processing biodegradation, contributing new growth, while self-sensing, origami-based robot supports seamless human-in-the-loop teleoperation system. This innovative approach represents paradigm shift in application soft systems, offering path toward more future aligning advanced functionalities environmental stewardship.

Abstract The rapid advancement of smart, flexible electronic devices has paralleled a surge in waste (e‐waste), exacerbating massive resource depletion and serious environmental pollution. Recyclable materials are extensively investigated to address these challenges. Herein, this study designs unique polyurethane (SPPUs) with ultra‐high strength up 60 MPa toughness 360 MJ m −3 . This synthetic SPPUs can be fully recycled at room temperature by using green solvents ethanol. Accordingly, the resultant SPPU‐Ni composites, created mixing ethanol‐dissolved solution nickel (Ni) powder, effectively combine flexibility recyclability electrical conductivity filler. Notably, work develops printable capacitive sensors (PCBS) through transcribing paste SPPUs‐Ni slurry onto PET film paper screen‐printing technology. devised PCBS have fast response time ≈50 ms, high resolution, multiple signal recognition capabilities. Remarkably, Ni powder only dissolving offers sustainable growing e‐waste problem recyclable electronics.
