  • Moisture detection apparatus
    Patent number: 9928723
    Abstract: A moisture detection apparatus can include a soft printed circuit board, a power supply, a processing unit, and a bendable body. The soft printed circuit board can include at least one capacitor. The power supply can be arranged to apply a voltage across the at least one capacitor. The processing unit can have one or more processors configured to detect a capacitance across the at least one capacitor and emit a moisture detection signal in response to a change the capacitance across the at least one capacitor. The soft printed circuit board is embedded in the bendable body. A kit can be comprised of the moisture detection and at least one bag assembly. Another kit can be comprised of the moisture detection and a receiving unit configured to receive the moisture detection signal.
