Conductive Hydrogels for Exogenous Sensing and Cell Fate Control

Advanced Materials, EarlyView.
We engineer electrically conductive hydrogels by combining sulfated glycosaminoglycans with semiconducting polymers. These hydrogels bind bioactive proteins, including growth factors, whose release or retention can be modulated by low‐voltage stimulation. The hydrogels are also integrated as 3D channels in organic electrochemical transistors as part of

Switched-transconductance techniques

Electronics Letters, 1993
A new circuit arrangement, described as a switched-transconductance (ST) circuit, comprising a continuous-time linear tunable transconductor and a discrete time current processor is proposed and its theoretical basis described. The approach allows impedance synthesis for tunable precision sampled-data applications.
