Patent number: 9418927Abstract: A stretchable electronic device is disclosed. In one aspect, the device includes at least one combination of a stretchable electronic structure having a first Young's modulus and a rigid or flexible electronic structure having a second Young's modulus higher than the first Young's modulus. The stretchable electronic structure and the rigid or flexible electronic structure may be electrically connected to each other by a semi-transition structure having a third Young's modulus with a value in a range between the first and the second Young's modulus.Type: GrantFiled: July 28, 2011Date of Patent: August 16, 2016Assignees: IMEC, Universiteit GentInventors: Fabrice Axisa, Jan Vanfleteren, Frederick Bossuyt

Patent number: 9247648Abstract: A stretchable electronic device is disclosed. In one aspect, the device has a stretchable interconnection electrically connecting two electronic components. The stretchable interconnection includes an electrically conductive channel having a predetermined first geometry by which the channel is stretchable up to a given elastic limit and a first flexible supporting layer provided for supporting the electrically conductive channel and having a predetermined second geometry by which the first supporting layer is stretchable. The predetermined second geometry has a predetermined deviation from the predetermined first geometry chosen for restricting stretchability of the electrically conductive channel below its elastic limit.Type: GrantFiled: July 28, 2011Date of Patent: January 26, 2016Assignees: IMEC, Univesiteit GentInventors: Jan Vanfleteren, Frederick Bossuyt, Fabrice Axisa

Patent number: 8182872Abstract: A method is provided for fabricating a porous elastomer, the method comprising the steps of: providing a predetermined amount of a liquid elastomer and a predetermined amount of a porogen; mixing the liquid elastomer and the porogen in vacuum until a homogenous emulsion without phase separation is formed; curing the homogenous emulsion until polymerizations of the emulsion is reached, thereby forming a cured emulsion; and removing the porogen from the cured emulsion. The method can advantageously be used for forming biocompatible porous elastomers and biocompatible porous membranes.Type: GrantFiled: September 21, 2009Date of Patent: May 22, 2012Assignees: IMEC, Universiteit GentInventors: Fabrice Axisa, Pritesh Dagur, Jan Vanfleteren
