Drift-free iontronic sensing enabled by a creep-free polyelectrolyte elastomer

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.Nature Materials, Published online: 10 April 2024; doi:10.1038/s41563-024-01851-xSoft pressure sensors drift under prolonged high stress because of the creep of soft materials, which causes inaccurate measurements.
