Book Description
Minimally invasive surgery (MIS) is becoming the preferred approach in several domains of surgery since it offers great reduction of pain, blood loss, post operative infection and patient's recovery time. However, because the MIS operating field is not directly accessible, surgeons face many difficulties when carrying out operations through small incisions. -- One of the major problems of MIS is the lack of effective force and tactile sensing capabilities. This potentially restricts surgeons in performing delicate surgical tasks. Tissue palpation which is easily done in traditional open surgery to investigate tissue properties and abnormalities cannot be effectively performed when operating through "keyholes". Over the past few years, research on force sensing in MIS has been conducted, aiming to overcome the lack of intuitive feel of tissue interaction. As a consequence, a number of force sensor prototypes have been developed. These include a uniaxial optical fibre force sensor and a non-metallic triaxial optical fibre force sensor that operates based on newly proposed intensity-modulated sensing schemes using bent-tip optical fibres. By introducing and researching a novel optical fibre sensing methodology that allows force measurements to be realised in a sensing system with very small dimensions, a miniature multi-axis force sensor has successively been fabricated. This sensor prototype has been tested measuring tissue interaction forces in an ex vivo tissue palpation experiment. The results show that the sensor is capable of measuring forces and identifying tissue stiffness. Tissue lesions such as tumours that are buried in a soft tissue organ and are stiffer than the surrounding tissue can be detected and localised using the proposed sensing device.

Book Description
Multi-Component Force Sensing Systems focuses on the design, development, decoupling, and applications of multi-component force sensing systems. Force and moment information can be used as feedback to form an automatic control system to accomplish efficient manipulation. The origins of force measurement and control can be traced back to the late 1970s. Since then, multi-component F/M (force/moment) sensing systems have been widely known and intensively studied. In the past few years, force measurement practices have been significantly affected by new tools (such as digital force gauges, virtual instrumentation, high speed data acquisition systems, etc.) as well as sophisticated measurement methods such as mechano-magnetic, mechano-optical, etc. However, this is the first book to provide an overview of the topic. It will be a useful reference for students in physics and engineering working with robotic sensing systems and robotic systems, in addition to researchers and those working within industry. This work was supported in part by the National Nature Science Foundation of China (NSFC 62073129 and 61673163). Features: • Explores the development of force/torque sensing systems • Provides real applications of the multi-component force/torque sensing systems • Contains executable code for decoupling algorithms About the Author: Qiaokang Liang is an Associate Professor with the College of Electrical and Information Engineering, Hunan University. He is currently the vice director of the Hunan Key Laboratory of Intelligent Robot Technology in Electronic Manufacturing and serving as the assistant director of the National Engineering Laboratory for Robot Vision Perception and Control. He received his Ph.D. degree in control science and engineering from the University of Science and Technology of China, Hefei, China, in 2011. His research interests include robotics and mechatronics, biomimetic sensing, advanced robot technology, and human–computer interaction.
