Abstract Next generation robot grippers should be equipped with tactile sensors providing a sense of touch similar to the human hand by measuring the local distribution of forces on the surface. In this Paper two realized sensor types are presented. The first type of tactile sensors are capacitive sensors.

2017 New Generation of CAS (NGCAS), 2017
In this paper, we present a novel event-driven Dynamic Tactile Sensor (DTS) for artificial devices. The sensor is based on the POSFET (Piezoelectric-Oxide-Semiconductor-Field-Effect-Transistor) as the tactile sensing device with the change detector (CD) circuit of the DVS (Dynamic Vision Sensor) [1] as a readout circuit.

The dynamic response of a tactile sensor
Proceedings., IEEE International Conference on Robotics and Automation, 2002Tests were performed on a thumb-shaped tactile sensor containing an 8 by 20 array of tactile elements. Each element measures the strain of the rubber finger material at a point below the surface of the finger. To characterize the finger behavior, a precision force application device was designed.

Verification of Tactile Sensor for Manipulator
2006 IEEE International Conference on Robotics and Biomimetics, 2006This paper describes the basic characteristics of a distributed-type tactile sensor that we developed for a manipulator. To create a dexterous manipulator, it is necessary to acquire reliable force information loaded on manipulator fingertips. In a previous paper, we illustrated that the tactile sensor can detect attached object movement. In this paper,

FERROPIEZOELECTRIC TACTILE SENSOR ARRAY
IFAC Proceedings Volumes, 1994Abstract A ferroelectric array sensor of a functional type for primary processing of tactile information, representing a homogeneous field of sensors in an active PZT ceramic substrate, has been developed. The results, obtained by physical-mathematical simulation of certain array sensor element, which is a non resonance piezoelectrical transformer ...

Touch and motion (tactile sensor)
Proceedings. 1988 IEEE International Conference on Robotics and Automation, 2003A 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

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 ...

A nephelometric tactile sensor
1997This 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
