Abstract: A system for non-invasive urinary activity monitoring may include a sticker that attaches to a urine bag. The sticker may include a metal layer shaped as an antenna. A device may cause a network analyzer to send a signal in a direction of the urine bag. The device may detect a shift in a resonant frequency of the antenna. The device may measure, based on the change in resonant frequency, an amount of fluid in the container. The device may measure, based on a change in the resonant peak amplitude, the conductivity of the fluid in the container.
