摘要：
In this letter, fully transient artificial synapses based on magnesium oxide memristors with short-term plasticity (STP) were proposed for the first time. Typical physiological reactions related to STP including pair-pulse facilitation and pair-pulse depression were demonstrated in such a transient synaptic device. Importantly, water-assisted transfer printing method was employed to transfer the dissolvable synaptic arrays onto bioresorbable poly (vinyl alcohol) substrate to form a fully transient system, which finally disintegrated in deionized water within 30 min. This transient synaptic emulator possesses great potential in security neuromorphic computing and environmentally resorbable applications.
