Abstract

Discloses is a system for the wireless transmission of energy and/or signals between spatially-separated regions with no electrically-conductive connection, the conversion of energy and/or signals into other forms of energy and/or forms of signal, and the application and/or detection of same in at least one peripheral region of said system. The system allows a wireless transmission of energy between at least two spatially-separated regions without an electrically-conductive connection, energy being supplied to at least one of these regions, transmitted to at least one additional region in a wireless manner, converted on demand into other forms of energy, and applied in a peripheral region of said system. Signals can be transmitted at the same time as energy is being transmitted.

First claim

What is claimed is:

1. A system for the wireless transmission of energy and/or signals between physically separate regions without electrically conductive connections, the conversion of the energy and/or signals into other energy forms and/or signal forms and the application and/or detection thereof in at least one peripheral region of the system, wherein the system comprises
at least one first transducer element by which magnetic alternating fields and/or magnetic signal forms are generable and/or detectable, the first transducer element being arranged in a first region, and
(a) at least one second transducer element that allows reciprocal, unidirectional or bidirectional conversion of energy of the magnetic alternating fields and/or of the magnetic signal forms into electrical energy and/or electrical signal forms, as well as at least one third transducer element that allows reciprocal, unidirectional or bidirectional conversion of the electrical energy and/or electrical signal forms into mechanical energy, the second transducer element and the third transducer element being arranged in a further region adjacent to the first region,
or
(b) at least one second transducer element by which the energy of the magnetic alternating fields generated by the first transducer element is convertible into thermal energy by hysteretic heating and/or eddy currents and/or by Joule heating of the second transducer element, as well as a thermal conductor element that forwards the thermal energy to a location of application, the second transducer element and the thermal conductor element being arranged in a further region adjacent to the first region,
or
(c) at least one second transducer element that allows reciprocal, unidirectional or bidirectional conversion of energy of the magnetic alternating fields and/or of the magnetic signal forms into electrical energy and/or electrical signal forms and/or thermal energy, as well as at least one fourth transducer element that is electrically and/or thermally conductively connected to the second transducer element and allows reciprocal, unidirectional or bidirectional conversion of the electrical energy and/or electrical signal forms and/or thermal energy into further energy forms, at least partially, and/or forwards these energy forms, the second transducer element and the fourth transducer element being arranged in a further region adjacent to the first region.

2. The system of claim 1 , alternative (a) or alternative (c), wherein second, third or fourth transducer elements are fixed alone or together with other transducer elements in a receptacle element.

3. The system of claim 1 , alternative (a), wherein the third transducer element is a piezoelectric transducer element.

4. The system of claim 1 , wherein a ferromagnetic core is arranged on or in a second transducer element.

5. The system of claim 1 , alternative (a), wherein the second transducer element and the third transducer element are directly electrically conductively connected.

7. The system of claim 1 , alternative (c), wherein a fourth transducer element converts and/or forwards at least some of the energy of at least one second transducer element and/or of at least one third transducer element into other energy forms.

8. The system of claim 1 , alternative (a) or alternative (c), wherein the second, third or fourth transducer elements are arranged to make a multiple conversion of magnetic energy into electrical, mechanical, kinetic energy and/or thermal energy achievable.

9. The system of claim 1 , wherein a first transducer element is an electrical coil having a ferromagnetic core, the ferromagnetic core being arranged in and/or on the electrical coil.

10. The system of claim 1 , wherein a first transducer element comprises a combination of multiple coils that have one or more associated ferromagnetic cores made of the same or different materials.

11. The system of claim 1 , wherein a receptacle element comprises at least one contour element present on it or the receptacle element is formed from an elastically deformable or acoustically conductive material.

12. The system of claim 1 , wherein at least part of the second transducer element, the third transducer element and/or the fourth transducer element is enclosed by a shaped body.

13. The system of claim 12 , wherein the shaped body is a prosthesis, an orthosis, an implant or an osteosynthetic aid.

14. The system of claim 12 , wherein the shaped body comprises at least one associated sensor or sensory-action body.

15. The system of claim 12 , wherein the shaped body comprises on it at least one receptacle for holding a sample.

16. The system of claim 1 , wherein each first transducer element provides magnetic fields and signal forms at frequencies in a range of from 10 Hz to 3000 Hz.

17. The system of claim 1 , wherein each first transducer element comprises at least one electrical coil to which a constant AC voltage is applied and at least one of the second, third or fourth transducer elements allows the conversion of the energy of the magnetic alternating fields and/or of the magnetic signal forms of the first transducer element into electrical energy and/or electrical signal forms and/or further energy or signal forms such that the last transducer element in a cascade realizes a physical gradient independently of frequency.
