摘要: The aim of this study is to develop a miniaturized tactile sensor which suitable for mounting on an endoscope the hardness detection submucosal tumors. size piezoelectric only 1.5 mm in diameter and hence it can be easily inserted endoscopy channel. To best our knowledge, first that compatible with endoscopy. We embedded different elastomers artificial tumors pig stomach simulating conditions human patients. experimental results show capable differentiating from normal tissues stomach. In addition, output voltage ratio proportional elastomer hardness. Consequently, proposed could provide more effective way detect tumor comparable state art endoscopic ultrasound.
