Lacour is a pioneer in the field of stretchable electronics and directs a laboratory at EPFL which specializes in the development of Soft BioElectronic Interfaces to enable seamless integration of neuroprosthetic devices into human tissues.

[7] The incredible degree of malleability and preserved electrical continuity that these thin gold films exhibit poised them to be essential in the future construction of 3D electronic circuits.

[8] After developing these elastic technologies at Princeton, Lacour implemented stretchable microelectrode arrays (SMEAs) into organotypic hippocampal slice culture models of traumatic brain injury (TBI) to measure neural activity prior to, during, and after a trauma-like event.

[9] Once Lacour began her position as a Research Fellow at the University of Cambridge, she collaborated with surgeons and other medical professionals to explore the potential of using her stretchable circuits and electrodes for nerve repair after injury.

[12] To further explore the potential of creating efficient and biocompatible in vivo neural interfaces, Lacour and her colleagues focused their attention to making microelectrode arrays more mechanically compliant.

[14] Lacour applied her thin, gold films onto silicone rubber and was able to create multifunctional, capacitative sensors that can detect and localize touch as well as record pressure and strain.

[10] In 2011, Lacour was recruited to the Swiss Federal Institute of Technology in Lausanne (EPFL) as a tenure track assistant professor of microtechnology and bioengineering at the School of Engineering.

[17] In 2010, Lacour was awarded a European Research Council Grant to support her initiative, ESKIN aimed at designing and improving current electronic systems to increase their stretchability to make them compatible with biological tissues while maintaining electrical functionality.

[18] Shortly after, Lacour was invited to give a TEDx talk at CERN In 2011 where she discussed her current research applying soft, flexible electronic circuits in addressing hearing loss in humans.

[20] By creating machines that have physical properties that are compatible with biological tissues, Lacour is able to establish a communication link between the external world, the device, and the brain to enhance the quality of life for people suffering from hearing loss.

[24] In its mechanical properties, the e-dura technology resembles biological dura mater, the thick protective coating around tissues of the central nervous system.

[24] e-dura accommodates deformations, since it is made from Lacour's stretchable, soft, electronic circuits, and this allows it to move with the body and prevent irritation and resistance that might lead to scarring and inflammation.
