Piezoelectric Polymer Transducer Arrays for Flexible Tactile Sensors

IEEE Sensors Journal, 2012
In this paper, we propose a novel technological approach for the implementation of large-area flexible artificial skin based on arrays of piezoelectric polymer transducers. Polyvinylidene fluoride (PVDF) transducers are chosen for the high electromechanical transduction frequency bandwidth (up to 1 kHz). A low-cost and scalable technique for extracting

Flexible Tactile Sensor Fabricated using Polymer Membrane

2006 5th IEEE Conference on Sensors, 2006
We present the fabrication process and the characteristics of a flexible tactile sensor by silicon micromachining, polymer processing and packaging technologies. The fabrication process for the tactile sensor was composed of in the fabrication of sensor chips and their packaging on the flexible printed circuit board (FPCB).

Flexible tactile sensors inspired by bio-mechanoreceptors

Biosensors and Bioelectronics
Mechanoreceptors 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 higher sensitivity, spatial resolution, and dynamic ranges.

Flexible Tactile Sensors for 3D Force Detection

Nano Letters
As tactile force sensing has become increasingly significant in the field of machine haptics, achieving multidimensional force sensing remains a challenge. We propose a 3D flexible force sensor that consists of an axisymmetric hemispherical protrusion and four equally sized quarter-circle electrodes.

Ferroelectret based flexible keyboards and tactile sensors

2011 - 14th International Symposium on Electrets, 2011
Ferroelectrets easily allow for the preparation of multilayer keyboards, where keys are digitally encoded with a ternary code. Contact electrode charging turned out to be a reliable way for the fast preparation of charge patterns on cellular polymers. A three layer keyboard, allowing for encoding 26 keys was fabricated to demonstrate the feasibility of

DISTRIBUTED FLEXIBLE TACTILE SENSOR USING PIEZOELECTRIC FILM

IFAC Proceedings Volumes, 2002
Abstract The prototype of the tactile sensor which has 8 × 8 array using piezoelectric film was fabricated. In the fabrication procedure, the electrode patterns and the common electrode of the thin conductive tape are attached to the both sides of the 28 um thickness piezoelectric film using conductive adhesive. The sensor is covered with polyester

Development of polyimide flexible tactile sensor skin

Journal of Micromechanics and Microengineering, 2003
We present the development of a polyimide-based two-dimensional tactile sensing array realized using a novel inverted fabrication technique. Thermal silicon oxide or Pyrex® substrates are treated such that their surfaces are OH group terminated, allowing good adhesion between such substrates and a spun-on polyimide film during processing through what ...

Research for improved flexible tactile sensor sensitivity

Journal of Mechanical Science and Technology, 2015
With the development of robotic technologies, in recent years these technologies have been applied to multidisciplinary fields of study. To operate similarly to a human being, many robot technologies require devices that can receive exterior stimulus, temperature, visual data, and the sense of smell, etc.

A novel integrated transparent flexible tactile sensor

2011 16th International Solid-State Sensors, Actuators and Microsystems Conference, 2011
In this work, we propose a novel capacitance tactile sensor with flexibility and transparency using polydimethylsiloxane (PDMS), polyethylene terephthalate (PET), and indium tin oxide (ITO) for based materials. This sensor can measure normal force and shear force simultaneously.
