Trampoline inspired stretchable triboelectric nanogenerators as tactile sensors for epidermal electronics

Nano Energy, 2021
Recent advances in flexible electronics have brought great promotions to the next generation of wearable devices, like electronic skin (E-skin). Nevertheless, the powering issue still limits the size, weight and cost for E-skin. Here, trampoline inspired

Multifunctional Tactile Sensors for Object Recognition

Advanced Functional Materials
Humans can grab and identify objects by capturing the features of physical shape, temperature, and material. However, creating artificial sensors with finger‐like tactile capabilities is challenging due to the contradiction between structural compliance ...

The dynamic response of a tactile sensor

Proceedings., IEEE International Conference on Robotics and Automation, 2002
Tests 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, 2006
This 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,

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

FERROPIEZOELECTRIC TACTILE SENSOR ARRAY

IFAC Proceedings Volumes, 1994
Abstract 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, 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
