Flexible tactile sensors inspired by bio-mechanoreceptors.
Biosensors & bioelectronicsMechanoreceptors in animals and plants play a crucial role in sensing mechanical stimuli such as touch, motion, stretch, and vibration. Learning from the mechanisms of mechanoreceptors may facilitate the development of bionic tactile sensors, leading to ...

Superresolution with an optical tactile sensor
2015 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2015Although superresolution has been studied to huge impact in visual imaging, it is relatively unexplored in tactile robotics. Here we demonstrate a novel optical sensor design (the TacTip) capable of achieving 40-fold localization superresolution to 0.1mm accuracy compared with a 4mm resolution between tactile elements.

A tactile sensor for laparoscopic cholecystectomy
Surgical Endoscopy, 1997During laparoscopic surgery, surgeons observe the three-dimensional abdominal cavity on a two-dimensional TV monitor, which is a limitation. Another limitation is that surgeons are unable to estimate the softness of organs or tissues during laparoscopic surgery as they are only allowed to use instruments which touch objects and direct palpation is not ...

The authors aim to realize a "Cell Tactile Sensor" which is integrated tactile receptors built by cultured cells. We regard the cells cultured on the PDMS membrane as the force receptors. We here report on interesting experimental results as follows: at first, we designed the positions of cells by self-organization which is due to mechanical ...

Tactile resonance sensors in medicine
Journal of Medical Engineering & Technology, 2009Tactile sensors in general are used for measuring the physical parameters associated with contact between sensor and object. Tactile resonance sensors in particular are based on the principle of measuring the frequency shift, Deltaf, defined as the difference between a freely vibrating sensor resonance frequency and the resonance frequency measured ...

Characterization and simulation of tactile sensors
2010 IEEE Haptics Symposium, 2010The response of a tactile sensor system (consisting of the sensors themselves and the material covering them) was characterized via robotic experiments. A point spread function model of this response was developed for typical interaction forces, allowing the use of graphics and imaging techniques respectively for simulating and interpreting tactile ...

Optimal tactile sensor placement
Proceedings, 1989 International Conference on Robotics and Automation, 2003By intelligently locating a tactile sensor with respect to a sensed object it is possible to minimize the number of sensed points required to identify or localize the object. The author applies principles of statistical decision theory to determine the optimal sensing location to constrain an object model, maximally based on any prior object ...
