Abstract Adopting compostable materials that return to nature akin to organisms can mitigate concerns regarding the ecological footprint associated with the widespread deployment of soft robots across various fields, including medicine, agriculture and environmental exploration.

1 Introduction 2D crystals have attracted considerable attention for their potential to suppress short-channel effects and enable tunable properties through lattice-mismatch-free integration via van der Waals (vdW) interactions.[1-6] Interface control in 2D crystals plays a critical role in various physical and electronic phenomena relevant to electrical devices. In particular, the metal–semiconductor junctions in 2D semiconductor-based devices have been the focus of intense research.

INTRODUCTION Common air pollutants and excess nitrates in topsoil react with environmental oxygen in the presence of ultraviolet (UV) radiation to produce nontrivial amounts of ground-level ozone (1). In turn, prolonged exposure to ground-level ozone causes irreversible oxidative damage to living plants and decreases the yield of many important food crops (1, 2). Ozone damage is predicted to become an increasing threat to global food production due to climate change (3, 4).
