Nature Materials, Published online: 17 April 2024; doi:10.1038/s41563-024-01875-3 The turn-off time is generally faster than the turn-on time in accumulation mode organic electrochemical transistors (OECTs), but the mechanism is less understood. Here the authors find different transient behaviours of turn-on and turn-off in accumulation mode OECTs, and ion transport is the limiting factor of device kinetics ..read more

2w ago
Nature Materials, Published online: 10 April 2024; doi:10.1038/s41563-024-01851-x Soft pressure sensors drift under prolonged high stress because of the creep of soft materials, which causes inaccurate measurements. Now, through molecular-level design, a leakage-free and creep-free polyelectrolyte elastomer is synthesized, and an iontronic sensor using the polyelectrolyte elastomer shows very low signal drift under a high static pressure ..read more
