Flexible sensors, circuits, and systems for bioelectronic interfacing

Bioelectronics is an emerging research area where human-made electronic systems interface, bidirectionally, with the electrical systems present in biology. Flexible electronics are a critical development for bioelectronic systems which can flex and stretch with the body. Printing based manufacturing approaches have been heavily investigated in recent years for creating bioelectronic systems, as screen printing can potentially provide scaled-up roll-to-roll based manufacturing while 3D and inkjet printing can potentially provide opportunities for personalisation. This paper presents a brief narrative review bioelectronics, the materials challenges in flexible sensors, circuits, and systems for bioelectronic interfacing, and examples of our approaches to tackling these challenges.
