摘要

在柔性透明衬底上观察了二元氧化锌和氧化钛夹芯忆阻器的痛觉行为。ITO/ZnO/TiOx/ITO/PEN器件通过施加超过0.9 V的脉冲幅度以及1ms的脉冲宽度来探测阈值行为。然而，通过保持相同的0.9 V脉冲幅度，伤害感受器通过施加比1 ms更高的脉冲宽度来越过公差。通过在有害刺激前超过10毫秒的长时间后测量该装置，也证实了基于记忆器的伤害感受器的松弛特性。伤害感受器在不同损伤电压下的抵抗反应验证了其痛觉异常和痛觉过敏行为。这种低成本的二元氧化物夹在记忆电阻器上的柔性伤害感受器是类人机器人应用的最佳选择。

Nanoscale Electronic Nociceptor using ZnO/TiOx Bilayer Memristor on a Flexible Substrate

Nociceptive behaviors of binary zinc oxide and titanium oxide sandwiched memristor are observed on a flexible transparent substrate. The ITO/ZnO/TiO_x/ITO/PEN device probes threshold behavior by applying beyond 0.9 V pulse amplitude along with an 1 ms pulse width. However, the nociceptor crossed the tolerance by applying a higher pulse width than 1 ms by maintaining the same 0.9 V pulse amplitude. The relaxation properties of the memristor-based nociceptor are also confirmed by measuring the device after a prolonged time of more than 10 ms prior to the noxious stimulation. The allodynia and hyperalgesia behavior of the nociceptor is validated from the resistance response with different injury voltages. The low-cost binary oxide sandwiched memristor-based flexible nociceptor can be the best alternative for humanoid robotic applications.
