Assistive technology involving auditory feedback is generally utilized by those who are visually impaired or have speech and language difficulties. Therefore, here we concentrate on an auditory human-machine interface that uses audio as a platform for conveying information between visually or speech-disabled users and society. We develop a piezoresistive tactile sensor based on a black phosphorous and polyaniline (BP@PANI) composite by the facile chemical oxidative polymerization of aniline on cotton fabric. Taking advantage of BP’s puckered honeycomb lattice structure and superior electrical properties as well as the vast wavy fabric surface, this BP@PANI-based tactile sensor exhibits excellent sensitivity, low-pressure sensitivity, reasonable response time, and good cycle stability. For a real-world application, a prototype device employs six BP@PANI tactile sensors that correspond to braille characters and can convert pressed text into audio on reading or typing to assist visually or speech-disabled persons. Overall, this research offers promising insight into the material candidates and strategies for the development of auditory feedback devices based on layered and 2D materials for human-machine interfaces.

涉及听觉反馈的辅助技术通常由视力受损或有言语和语言困难的人使用。因此，我们在这里专注于听觉人机界面，它使用音频作为视觉或语言障碍用户与社会之间传达信息的平台。我们通过苯胺在棉织物上的简便化学氧化聚合，开发了一种基于黑磷和聚苯胺 (BP@PANI) 复合材料的压阻式触觉传感器。利用BP的褶皱蜂窝晶格结构和优异的电性能以及广阔的波浪织物表面，这种基于BP@PANI的触觉传感器具有出色的灵敏度、低压灵敏度、合理的响应时间和良好的循环稳定性。对于实际应用，原型设备采用六个 BP@PANI 触觉传感器，这些传感器与盲文字符相对应，可以在阅读或打字时将按下的文本转换为音频，以帮助有视觉障碍或语言障碍的人。总的来说，这项研究为开发基于分层和二维人机界面材料的听觉反馈设备的候选材料和策略提供了有前途的见解。
