Figure 1. Soft biodegradable wireless sensing platform for long-distance and wide-angle physiological monitoring. (A) Schematic comparison of a standard LC readout system and the pole-moving sweeping readout system; (B) Phase-frequency response curves at readout distances of 15 cm and 25 cm; (C) Exploded-view schematic of the folded multilayer strain sensor structure; (D) Schematic of in vivo implantation of temperature and pressure sensors in the abdominal cavity of a horse. (E) Schematic and photograph of ex vivo strain sensing on a pig heart; (F) Schematic of a pressure sensor placed between human abdominal surface and fresh pork to simulate deep-tissue sensing; (G) Sequential optical images (Day 0-35) and resonant frequency stability over time.
