Touch and motion (tactile sensor)

Proceedings. 1988 IEEE International Conference on Robotics and Automation, 2003
A tactile sensor has been developed which uses a layer of photoelastic material as its primary sensing element. This sensor has several desirable characteristics, including very high resolution, adaptable shape, and edge enhancement. Interestingly, the sensor has a similar sensing mechanism to human skin. A mathematical model has been developed for the

Functional Tactile Sensor Based on Arrayed Triboelectric Nanogenerators

Advanced Energy Materials
In the era of Internet of Things (IoT) and Artificial Intelligence (AI), sensors have become an integral part of intelligent systems. Although the traditional sensing technology is very mature in long‐term development, there are remaining defects and ...

Tactile resonance sensors in medicine

Journal of Medical Engineering & Technology, 2009
Tactile 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, 2010
The 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 ...

A tactile sensor for laparoscopic cholecystectomy

Surgical Endoscopy, 1997
During 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 ...

A nephelometric tactile sensor

1997
This paper describes the design and construction of a novel robot tactile sensor array. The sensory principle employed is the measurement of diffuse reflected light emanating from a turbid liquid when the liquid is illuminated by a collimated light source. External objects pressed against the sensor vary the thickness of a layer of turbid liquid. Light

Tactile Behaviors with the Vision-Based Tactile Sensor FingerVision

International Journal of Humanoid Robotics, 2019
This paper introduces a vision-based tactile sensor FingerVision, and explores its usefulness in tactile behaviors. FingerVision consists of a transparent elastic skin marked with dots, and a camera that is easy to fabricate, low cost, and physically robust.

Toward Living Tactile Sensors

2013
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 ...
