Biopolymer Cryogels for Transient Ecology‐Drones

Aerial robots can autonomously collect temporal and spatial high-resolution environmental data. This data be utilized to develop mathematical ecology models understand the impact of climate change on habitat. In case drone malfunction, incorporated materials threaten vulnerable environments. The recent introduction transient robotics enables development biodegradable, environmental-sensing drones capable degrading in their environment. However, manufacturing methods for are rarely discussed. Herein, a framework material selection process featuring biopolymer-based, high-strength composite cryogels, printed carbon-based electronics highlighted. It is found that gelatin- cellulose-based cryogels mechanically outperform other biopolymer composites while having homogeneous microstructure high stiffness-to-weight ratio. selected used manufacture flying-wing air-frame, sensing skin measuring elevons’ deflection angles as well ambient temperature. demonstrated results how gelatin–cellulose lightweight drones, printing carbon-conductive viable method designing sustainable, integrated sensors. proposed guide rapidly robots, eco-friendly capabilities.
