Claim 0:
1. A sensing device, comprising:
a sensing module configured to obtain a measurement data of an object to be measured;
a first processing module coupled to the sensing module and configured to receive the measurement data of the object to be measured from the sensing module; and
a power module coupled to the sensing module and the first processing module, including:
a first inductance coil;
a rectifying circuit operatively connected to an output of the first inductance coil;
a filtering circuit operatively connected to an output of the rectifying circuit; and
a DC-DC transforming circuit operatively connected to an output of the filtering circuit, the power module configured to produce a supply voltage based on a magnetic field generated by an electromagnetic device and processed by a signal processing unit before powering the sensing module and the first processing module.
