New glass broken alarm

    Recently, a break or rupture in a timely manner when the alarm of a new type of glass available.
    The entire surface of the glass with unilateral conductive to the glass on the weak-current, once they are broken or cracked, its electrical conductivity of the area on the smaller, resistance will increase. Through small changes to the current judgement of the resistance to change and then determine whether a glass anomaly. Once confirmed, it will pass the relevant alarm devices.
    This conductive glass from the two single-sided adhesive from glass, the glass is about two conductive side of the face-to-face stick together. Therefore, people will not come into contact with a conductive part of the risk of electric shock.
