1. A system for monitoring moving parts in a machine, the system comprising:
a base unit for powering and generating commands, the base unit comprising:
a generator for generating controllable frequency;
an impedance unit to resonate impedance with a matching frequency;
a controller for modulating the impedance with commands, further the controller decodes changes in the impedance;
a first electrode to emit an alternating electric field from the resonating frequency received from the impedance unit;
a mixer for combining data with the frequency; and
a communication unit for communicating the data and commands over a communication network;
an electronic circuitry attached to the parts of the machine and capacitively coupled with the base unit, wherein the electronic circuitry comprising:
a coupling electrode influenced by the modulated alternating electric field emitted from the controller via the first electrode;
a harvester for converting the alternating electric field into a DC energy;
an analyzer to analyze the change in impedance of the provided alternating electric field caused by the parts of the machine, further the analyzer outputs the analyzing results as data, wherein the analyzer comprising:
an array of electronic switches;
an analog unit configurable with the electronic switches; and
an integrated digital unit for switching and configuring signals for the analog unit under the control of the controller;
a modulator for modulating the alternating electric field with the data, wherein the modulated data is forked out by the mixer and processed by the controller; and
a floating electrode coupling to ground potential.
