[2026]_Bioelectronic Hydrogels

Soft, electrically active hydrogels are promising candidates for 3D bioelectronics.¹ However, there is still gap to obtain conductive hydrogels with spatial and temporal electrical resolution. Enzymatic hydrogel systems show potential of combining efficient mixed ionic-electrical conductivity with tailored bio-material properties for interfacing human tissue and record/stimulate its biological activity.²

Duration: 12 month
