In this paper, with the goal of addressing the lack of tactile feedback in colorectal cancer (CRC) polyps diagnosis using a colonoscopy procedure, we propose the design and fabrication of a novel soft and inflatable strain-based tactile sensing balloon (SI-STSB). The proposed soft sensor features a unique stretchable sensing layer - that utilizes a liquid metal injected within spiral-shape microchannels of a stretchable substrate - and is integrated with a unique inflatable balloon mechanism. The proposed SI-STSB has been thoroughly characterized through different calibration experiments. Results demonstrate a phenomenal adjustable sensitivity with low hysteresis behavior under different experimental conditions for this sensor making it a great candidate for enhancing the existing diagnosis procedures.
在本文中,为了解决在结肠镜检查过程中结直肠癌(CRC)息肉诊断缺乏触觉反馈的问题,我们提出设计并制造一种新型的基于应变的柔软可充气触觉传感气球(SI-STSB)。所提出的软传感器具有独特的可拉伸传感层,该传感层利用注入可拉伸基板螺旋形微通道内的液态金属,并与独特的可充气气球机制集成在一起。所提出的SI-STSB已通过不同的校准实验进行了全面表征。结果表明,该传感器在不同实验条件下具有显著的可调灵敏度和低滞后行为,使其成为增强现有诊断程序的理想候选者。
