“…During needle insertion, many authors presented optical sensors to measure force or pressure information based on the varying intensity or phase from a light signal [ 63 , 64 , 93 , 94 , 96 , 97 ]. An optical sensor is able to acquire force with multiple DOFs and in high-intensity magnetic fields for imaging with high sensitivity, reproducibility and no hysteresis [ 136 ].…”

Robot-assisted surgery is of growing interest in the surgical and engineering communities. The use of robots allows surgery to be performed with precision using smaller instruments and incisions, resulting in shorter healing times. However, using current technology, an operator cannot directly feel the operation because the surgeon-instrument and instrument-tissue interaction force feedbacks are lost during needle insertion. Advancements in force feedback and control not only help reduce tissue deformation and needle deflection but also provide the surgeon with better control over the surgical instruments. The goal of this review is to summarize the key components surrounding the force feedback and control during robot-assisted needle insertion. The literature search was conducted during the middle months of 2017 using mainstream academic search engines with a combination of keywords relevant to the field. In total, 166 articles with valuable contents were analyzed and grouped into five related topics. This survey systemically summarizes the state-of-the-art force control technologies for robot-assisted needle insertion, such as force modeling, measurement, the factors that influence the interaction force, parameter identification, and force control algorithms. All studies show force control is still at its initial stage. The influence factors, needle deflection or planning remain open for investigation in future.

This article is focused on reviewing the current state-of-the-art of optical fibre pressure sensors for medical applications. Optical fibres have inherent advantages due to their small size, immunity to electromagnetic interferences and their suitability for remote monitoring and multiplexing. The small dimensions of optical fibre-based pressure sensors, together with being lightweight and flexible, mean that they are minimally invasive for many medical applications and, thus, particularly suited to in vivo measurement. This means that the sensor can be placed directly inside a patient, e.g., for urodynamic and cardiovascular assessment. This paper presents an overview of the recent developments in optical fibre-based pressure measurements with particular reference to these application areas.

Autonomous grasping operations in dynamical environments are key elements of solutions for Factory-of-the-Future scenarios. The manipulator has to cope with a broad variety of objects with different shapes, materials and uncertain poses but at the same time it should provide reliable grasping and placement operations. Within this context, tactile sensors mounted directly on the grippers are a promising solution for monitoring the grasping process. They operate independently from light or line of sight configurations, thus offer a new object detection modality,besides optical-based systems. We receive an imprint of the grasped object with a spatial resolution according to the sensor pattern. However, in case of grippers with a flexible structure and material, this method generates spurious measurements if the gripper is deformed during a manipulation process. This effect disturbs the evaluation of the gripper's state or object position.In this paper, we develop the specification of a tailored tactile sensor configuration able to handle gripper deformations. Based on the results we present a proof-of-concept implementation.
