Video-tactile pneumatic sensor for soft tissue elastic modulus estimation
BACKGROUND A new sensor for estimating elasticity of soft tissues such as a liver was developed for minimally invasive surgery application. METHODS By measuring deformation and adjusting internal pressure of the pneumatic sensor head, the sensor can be used to do palpation (indentation) of tissues with wide range of stiffness. A video camera installed within the sensor shell is used to regist...
متن کاملA Pneumatic Tactile Sensor for Co-Operative Robots
Tactile sensors of comprehensive functions are urgently needed for the advanced robot to co-exist and co-operate with human beings. Pneumatic tactile sensors based on air bladder possess some noticeable advantages for human-robot interaction application. In this paper, we construct a pneumatic tactile sensor and apply it on the fingertip of robot hand to realize the sensing of force, vibration ...
متن کاملStatistical Analysis of Instantaneous Effect of Polarized He-Ne Laser Radiation on the Elastic Modulus of Soft Biological Tissue
Introduction: This work is dedicated to investigating the effect of applying polarized He-Ne laser beam (λ= 632 nm, 10 mW, 1 j/cm2) with polarization direction perpendicular to the stress direction on the tensile strength of biological tissue (elasticity index of the Pleura 10*4*0.1 mm). Method and Material: The optimized characteristics of the laser illumi...
متن کاملSoft Tissue Elastic Modulus Measurement and Tumor Detection Using Piezoelectric Fingers
We have investigated probing breast tumor in a lumpectomy sample using a newly developed piezoelectric finger (PEF). PEF is a piezoelectric cantilever that consists of a top driving piezoelectric lead zirconate titanate (PZT) layer and a bottom sensing PZT layer sandwiched to a middle stainless steel layer. A PEF can both apply a force and detect the corresponding displacement in one single dev...
متن کاملDesign and Construction of a New Capacitive Tactile Sensor for Measuring Normal Tactile Force
This paper presents the design, construction and testing of a new capacitive tactile sensor for measurement of normal tactile force. The operation of proposed sensor has been investigated in ASTABLE and MONOSTABLE circuits. According to the results of these circuits the deviation of ASTABLE circuit results is less than MONOSTABLE circuit results. In addition, the results obtained from ASTABLE c...
