Claims29
A device comprising:
- a) a polymeric material comprising the following properties:
- i) a dielectric constant of about 2 to 4 at 60 Hz;
- ii) an elongation break at about 10% to 300%;
- iii) a water absorption rate of about 0.01% to 0.10% per 24 hrs;
- and
- b) a conductive material
- wherein the conductive material is encapsulated in the polymeric material and wherein the device generates an electromotive force when contacted with a modulated magnetic field, or generates a magnetic field when contacted with an electromotive force.
