Distributed multitudes of bio-inspired, biodegradable Lagrangian sensors for environmental sustainability

Bioresorbable distributed Lagrangian sensors may enable environmentally sustainable spatio-temporal mapping of acute disasters through integrated dynamic and chemical sensing. We summarize recent work in bioinspired, ultraminiature structures, sensing targets, wireless communication and power strategies, and conclude with emerging directions for advancing these sensing platforms. Biodegradable collections of Lagrangian sensors may enable sustainable mapping of environmental parameters. The authors evaluate bioinspired designs, sensing targets, communication methods, power supply strategies, and future directions for these platforms.
