Within the bioelectronics field, miniaturized devices with high conformability to complex anatomical structures and wireless data transfer capabilities are highly desirable. Although smart (wireless network-connected) medical devices have become accepted both by patients and practitioners, their form factor (shape, size, and physical specifications) remains a challenge.
In this context, we are exploring novel device materials and their associated technologies to design and manufacture soft bioelectronic interfaces. They are broadly defined as microfabricated devices with mechanical properties suited to comply the soft and dynamic biological tissues. We engineer sets of materials that combine mechanical compliance, electrical function, and biocompatibility. We borrow and adjust microfabrication techniques to manipulate and integrate the soft materials into devices. We develop advanced multimodal characterization tools to establish the performance and reliability of the soft interfaces and advance their translation towards clinical use. Our research is by essence interdisciplinary and offers exciting opportunities, especially in wearable electronics and neuroprosthetic medicine.
