Seoul National University Develops Biodegradable Robotic Fingers That Fertilize Soil

Researchers at Seoul National University have created soft, stretchable robotic fingers designed for surgical use that decompose in soil and act as natural fertilizer. The device's body is made from polyglycerol sebacate, a plant-based elastomer derived from glycerol and sebacic acid, while its electronic components use transient inorganics that dissolve under specific conditions. In tests, the fully composted system, including materials like silicon and magnesium, supported oat germination without hindering growth. This innovation addresses environmental concerns by reducing electronic waste from single-use medical devices and sensors. The study, published in a scientific journal, aims to enable technology that benefits both human health and the planet.
