Flexible Capacitive Synapse with Ultralow Energy Consumption Enabled by a Freestanding BaTiO <sub>3</sub> Membrane
membrane that can be readily transferred to a variety of substrates for constructing a van der Waals-based capacitive artificial synapse. The fabricated device demonstrated outstanding environmental stability and retained a clear ferroelectric hysteresis even at an operating voltage of 50 mV, enabling ultralow energy consumption. Integration into a synapse-based system for electrocardiogram classification, including arrhythmia recognition, further highlights the applicability of flexible functional oxide thin films for high-performance wearable sensing technologies.
