Abstract

A peel and stick electronic system comprises a silicone body, and at least one electronic unit operatively connected to the silicone body. The electronic system is produce by providing a silicone layer on a substrate, providing a metal layer on the silicone layer, and providing at least one electronic unit connected to the metal layer.

Claims

1. A method of fabricating an electronic apparatus, consisting essentially of the steps of:

providing a silicone layer on a matrix,

providing a metal layer on said silicone layer,

providing a second layer of silicone on said silicone layer,

providing at least one electronic unit connected to said metal layer, and

removing said electronic apparatus from said matrix.

2. The method of fabricating an electronic apparatus of claim 1 wherein said silicone layer and said second layer of a silicone comprise poly(dimethylsiloxane).

3. The method of fabricating an electronic apparatus of claim 1 wherein said silicone layer and said second layer of a silicone provide a thin flat polymer body.

4. The method of fabricating an electronic apparatus of claim 1 wherein said at least one electronic unit comprises an electrode array.
