<p>The invention relates to an activation system comprising a reception device for receiving an activation signal (SIGA), and an activation circuit (4) for activating an electric circuit (5). The invention is characterised in that at least one pyroelectric element (3) is connected to the reception device (1) and to the activation circuit (4). Said pyroelectric element can be heated by means of the activation signal (SIGA) in such a way that a voltage high enough to actuate the activation circuit (4) can be produced in the pyroelectric element.</p> |
