Water and ion ingress are challenging to quantify, especially in miniaturized microsystems. Here, Mariello et al. report a wireless and battery-free flexible water-permeation sensing platform, using backscatter communication and Mg-based microsensors for in-situ monitoring of implantable bioelectronics.
