1. A low power sensor, comprising:

  • a hollow enclosure;

    an antenna disposed external to said hollow enclosure and configured to collect emission of electromagnetic energy;

    a circuit disposed within said hollow enclosure and comprising a low noise amplifier (LNA) connectable to said antenna, and an analog to digital converter (ADC) in a connection with said LNA;

    circuit connections connecting, during use of said sensor, said circuit to each of said antenna, a source of electric energy and a signal processing component;

    a connection between said hollow enclosure and an enclosure of an integrated circuit (IC), said connection comprises an adhesive layer disposed on an exterior surface of said hollow enclosure, said antenna being encapsulated in said adhesive layer, whereby said antenna is disposed between said sensor and the IC during use of said sensor; and

    said sensor configured to at least measure a low-level electromagnetic energy emitted from the IC.
