Olfactory plays an important role in virtual reality technology. In this work, a bionic fibrous membrane (BFM) integrated with the function of electrostatic field accelerated evaporation (EFAE) is applied for realizing the virtual olfactory generation (VOG) system. The BFM is capable of self-driven unidirectional liquid transmission and EFAE process is induced on BFM by using an ultrafast voltage-elevation triboelectric nanogenerator (UVE-TENG). The output voltage from UVE-TENG can reach 8 kV within 40 ms, which is enough to maintain all of the functions of VOG system. Meanwhile, the output current from UVE-TENG is smaller than 1 μA, leading to a safe and human compatible system. The flow rate of the volatile liquid spray from the system emitter can reach 0.1 μl/s, and the average evaporation rate of the BFM device with integrated EFAE function is 0.12 mg/s. Accordingly, the user of this VOG system can feel the generation of odor within 3 s, while the switching of different odor channels can be wirelessly controlled by a mobile phone. This VOG system enhances the user's immersive and interactive experience for virtual reality technology. The similar system composed of UVE-TENG, reed switch, BFM and EFAE devices also has potential application value in assisted breathing treatment and nasal delivery.

基于仿生纤维膜和静电场加速蒸发的自供电虚拟嗅觉生成系统

嗅觉在虚拟现实技术中起着重要作用。在这项工作中，采用集成了静电场加速蒸发（EFAE）功能的仿生纤维膜（BFM）来实现虚拟嗅觉生成（VOG）系统。BFM 能够自驱动单向液体传输，并且通过使用超快电压升高摩擦纳米发电机 (UVE-TENG) 在 BFM 上诱导 EFAE 过程。UVE-TENG 的输出电压可在 40 ms 内达到 8 kV，足以维持 VOG 系统的所有功能。同时，UVE-TENG 的输出电流小于 1 μA，是一个安全且与人体兼容的系统。系统发射器喷出的挥发性液体流量可达0.1μl/s，集成EFAE功能的BFM装置的平均蒸发速率为0.12 mg/s。因此，该VOG系统的用户可以在3秒内感受到气味的产生，同时可以通过手机无线控制不同气味通道的切换。该VOG系统增强了用户对虚拟现实技术的沉浸式交互体验。由UVE-TENG、干簧管、BFM和EFAE装置组成的类似系统在辅助呼吸治疗和鼻腔给药方面也具有潜在的应用价值。
