Summary

The course is an introduction to the emerging field of flexible (bio)electronics. It provides an overview of the materials and processes used to design and manufacture flexible circuits and sensors. Applications encompass flexible sensors, biointerfaces, human-machine interfaces and neuroprosthetic

Content

Because of the interdisciplinarity nature of the subject, the course content includes concepts from many disciplines in engineering (electrical, material sciences, mechancial, bio- and biomedical engineering).  The three main components of the cours are: (1) key concepts in bioelectronics and biomechanics, (2) Materials and microfabrication, (3) Bioelectronic devices and applications. This course presents the main steps to follow to design flexible bioelectronic interfaces.
