Abstract：
Nociceptor is an important receptor in the organism\'s sensory system; it can perceive harmful stimuli and send signals to the brain in order to protect the body in time. The injury degree of nociceptor can be divided into three stages: self-healing injury, treatable injury, and permanent injury. However, the current studies on nociceptor simulation are limited to the self-healing stage due to the limitation of the untunable resistance switching behavior of memristors. In this study, we constructed Al/2DPTPAK+TAPB/Ag memristor arrays with adjustable memory behaviors to emulate the nociceptor of biological neural network of all three stages. For this purpose, a PDMS/AgNWs/ITO/PET pressure sensor was assembled to mimic the tactile perception of the skin. The memristor arrays can not only simulate all the response of nociceptor, i.e., the threshold, relaxation, no adaptation, and sensitization with the self-healing injury, but can also simulate the treatable injury and the permanent injury. These behaviors are both demonstrated with a single memristor and in the form of pattern mapping of the memristor array.
摘要：
伤害感受器是生物体感觉系统中的重要受体,它能感知有害刺激并向大脑发送信号,以便及时保护身体。伤害性感受器的损伤程度可分为三个阶段:自愈损伤、可治疗的伤害，和永久性伤害。然而,由于忆阻器的不可调谐电阻开关行为的限制，目前对伤害性感受器模拟的研究仅限于自愈阶段。在这项研究中,我们构建了具有可调记忆行为的Al/2DPTPAKTAPB/Ag忆阻器阵列，以模拟所有三个阶段的生物神经网络的伤害感受器。为此,组装PDMS/AgNWs/ITO/PET压力传感器以模拟皮肤的触觉感知。忆阻器阵列不仅可以模拟伤害性感受器的所有响应，即，门槛,放松,没有适应,和自愈损伤的敏感性，但也可以模拟可治疗的伤害和永久性伤害。这些行为都用单个忆阻器以及以忆阻器阵列的模式映射的形式来展示。
