    Under certain conditions, some battery chemistries are at risk of thermal runaway, leading to cell rupture or combustion.As thermal runaway is determined not only by cell chemistry but also cell size, cell design and charge, only the worst-case values are reflected here.

  4. Vibrator (electronic) - Wikipedia

    en.wikipedia.org/wiki/Vibrator_(electronic)

    Since vibrators were typically plugged into sockets mounted directly on the radio chassis, the vibration could potentially be mechanically coupled to the chassis, causing it to act as a sounding-board for the noise. To prevent this, the sound-deadening lining inside the can was sometimes made thick enough to support the vibrator's components by ...

    Insides of a slip-stick piezoelectric motor. Two piezoelectric crystals are visible that provide the mechanical torque. [1]A piezoelectric motor or piezo motor is a type of electric motor based on the change in shape of a piezoelectric material when an electric field is applied, as a consequence of the converse piezoelectric effect.

    An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections [1] for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. [2] The terminal marked negative is the source of electrons.
