1. A system for measuring charges propagating through a biological object, the system comprising:
an implantable medical device adapted to be inserted into the biological object;
an electronic implant adapted to be attached to the implantable medical device, wherein the electronic implant measures, processes and communicates electrical charges;
at least one transponder configured on the implantable medical device, wherein the transponder is configured to convert mechanical waves propagating through the biological object into bio-electrical charges, and output the bio-electrical charges such that the bio-electrical charges propagate through the biological object to be received by the electronic implant; and
an external electronic hub device configured to provide electrical charges to propagate through the biological object, the external hub device comprising:
a controller configured to contactlessly power the electronic implant, and communicate data with the electronic implant;
a frequency generator configured to generate alternating charges;
a resonator configured to resonate and receive modulated data from the electronic implant, the modulated data representing digitized information;
a filter unit configured to mix data received from the controller with the alternating charges, and filter and direct data from the electronic implant to the controller; and
an electrode configured to emit the alternating charges as an alternating electric field that propagates through the biological object and influences the electronic implant;
wherein the electronic implant comprises an arrangement of sub-circuits comprising:
an electrode configured to receive the alternating electric field emitted by the external electronic hub device and propagating through the biological object, and to receive bio-electrical charges propagating through the biological object, including the bio-electrical charges output by the transponder;
an energy convertor configured to harvest and rectify the received alternating electric field to provide a DC energy, store the DC energy and provide differential voltages;
an amplifier configured to amplify the received bio-electrical charges while suppressing electrical influence of the alternating electric field, and create an amplified analog value representing the received bio-electrical charges;
an analog/digital converting logic circuit configured to generate digitized information from the amplified analog value; and
a modulator configured to generate modulated data to be received by the electronic hub device by modulating the alternating electric field received from the electronic hub device with the digitized information.
