A CMOS Compatible Micromachined Tactile Fingerprint Sensor
We present in this paper a novel tactile fingerprint sensor composed by a single row of microbeams realized by the way of front side bulk micromachining from a standard CMOS circuit. When the user passes his finger on the sensor, the ridges and the valleys that compose the fingerprint induce deflections in the different microbeams. Using a piezoresistive gauge placed at their base, the deflecti...
متن کاملPolymer micromachined multimodal tactile sensors
We present the design, fabrication process, and characterization of a multimodal tactile sensor made of polymer materials and metal thin film sensors. The multimodal sensor can detect the hardness, thermal conductivity, temperature, and surface contour of a contact object for comprehensive evaluation of contact objects and events. Polymer materials reduce the cost and the fabrication complexity...
متن کاملDynamic Contact Sensing of Soft Planar Fingers with Tactile Sensors
This paper focuses on a method of estimating contact force dynamically between environment and an object, which is grasped by the soft planar fingers with tactile sensors. The external contact force acting on the grasped object causes the tactile sensors to generate the displacement distributions and the force distributions. We present a method of dynamic tactual image acquisitions for both dis...
متن کاملDesign Optimisation of a Magnetic Field Based Soft Tactile Sensor
This paper investigates the design optimisation of a magnetic field based soft tactile sensor, comprised of a magnet and Hall effect module separated by an elastomer. The aim was to minimise sensitivity of the output force with respect to the input magnetic field; this was achieved by varying the geometry and material properties. Finite element simulations determined the magnetic field and stru...
متن کاملVideo-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...
