ELECTRONIC MEDICAL DEVICES AND METHODS

The present disclosure provides an elastic electronic circuit adapted to provide three dimensional elasticity while conforming to the curved or angled structures of a swellable medical device, such as a hydrogel or silicone hydrogel contact lens. The elastic electronic circuit can include a first pattern for flexibility in a first dimension, a second pattern for flexibility in a second dimension, and a third pattern for flexibility in a third dimension. Alternatively, the elastic circuit can include a first pattern for flexibility in a first dimension and a second pattern for flexibility in a second dimension. The resulting three-dimensional elasticity enables the use of electronic circuits on soft contact lenses, where manufacture and use will cause the lenses and circuits to swell and shrink. Furthermore, the electronic circuit will not distort the vision correction of the contact lens or otherwise cause discomfort or other negative side effects.
