| Abstract: | Interaction force between needle and biological tissue is studied. The puncture force is modeled. A force sensing detection system of biological soft tissues is built.The system consists of both hardware and software components.The needle is powered by high-precision displacement platform made in German.The piezoresistive force sensor is used for force signals detecting and the acquisition card is used to collect force signal in real-time. The LabVIEW is used to control motor movement and data acquisition. With experimental platform,the needle penetration experiment is carried out.MATLAB is used for experimental data processing and analysis,the puncture force-displacement curve is formed and the relationship between various factors and force-displacement curve is conducted. |
