Biomimetic tactile sensor
TLDR
Disclosed is a tactile sensory system consisting of set of sensors that work by measuring impedance among plurality of electrodes that is related to canonical physical representations used to describe stimuli to be sensed.Abstract:
Disclosed is a tactile sensory system consisting of set of sensors that work by measuring impedance among plurality of electrodes. The electrodes are deployed on a substantially rigid structure that is protected form the direct contact with external objects by overlying deformable structures. These mechanical structures have similarities to the biological relationships among the distal phalanx, overlying finger pulp and covering skin and nail. Signal information is extracted form these sensors that is related to canonical physical representations used to describe stimuli to be sensed.read more

Directions Toward Effective Utilization of Tactile Skin: A Review
TL;DR: The state of the art and the research issues in tactile sensing, with the emphasis on effective utilization of tactile sensors in robotic systems are surveyed, recognizing the fact that the system performance tends to depend on how its various components are put together.
Journal ArticleDOI
Biomimetic Tactile Sensor Array
TL;DR: The performance of robotic and prosthetic hands in unstructured environments is severely limited by their having little or no tactile information compared to the rich tactile feedback of the human hand, so means to optimize the dynamic range of individual electrode sensors by texturing the inner surface of the silicone skin.

Artificial skin and elastic strain sensor
Robert J. Wood,Yong-Lae Park,Carmel Majidi,Bor-rong Chen,Leia Stirling,Conner James Walsch,Radhika Nagpal,Diana Young,Yigit Menguc +8 more
TL;DR: An elastic strain sensor can be incorporated into an artificial skin that can sense flexing by the underlying support structure of the skin to detect and track motion of the support structure as discussed by the authors, which can be used to provide advanced sensing.

Roles of glabrous skin receptors and sensorimotor memory in automatic control of precision grip when lifting rougher or more slippery objects
Roland S. Johansson,G. Westling +1 more
TL;DR: The present paper deals quantitatively with the regulation of the coordination between the grip force and the vertical lifting force, denoted as the load force, while small objects were lifted, positioned in space and replaced by human subjects using the pinch grip.

Factors influencing the force control during precision grip.
G. Westling,Roland S. Johansson +1 more
TL;DR: It was found that the applied grip force was critically balanced to optimize the motor behaviour so that slipping between the skin and the gripped object did not occur and the grip force did not reach exeedingly high values.

System for determining the location and orientation of an invasive medical instrument
TL;DR: In this paper, a locating system for determining the location and orientation of an invasive medical instrument relative to a reference frame is proposed, consisting of a plurality of field generators (18, 20, 22) which generate known, distinguishable fields, preferably continuous AC magnetic fields, in response to drive signals, and a set of sensors (30, 32, 34, 34) which proximate the distal end of the invasive medical device and generate sensor signals in response.
