Tactile imaging, as a medical imaging modality, translating the sense of touch into a digital image is based on the tactile sensors. Tactile imaging closely mimics manual palpation, since the probe of the device with a pressure sensor array mounted on its face acts similar to human fingers during clinical examination, deforming soft tissue by ...
The third and final tactile sensor type is a low spatial resolution sensor which has similar tactile acuity as the skin on one's back or arm. [28] These sensors can be placed meaningfully throughout the surface of a prosthetic or a robot to give it the ability to sense touch in similar, if not better, ways than the human counterpart. [28]
The goal of soft robotics is the design and construction of robots with physically flexible bodies and electronics. In some applications, softness is restricted to a localized region of a machine. For example, rigid-bodied robotic arms can employ soft end effectors to gently grab and manipulate delicate or irregularly shaped objects. [ 3 ]
Electronic skin refers to flexible, stretchable and self-healing electronics that are able to mimic functionalities of human or animal skin. [1] [2] The broad class of materials often contain sensing abilities that are intended to reproduce the capabilities of human skin to respond to environmental factors such as changes in heat and pressure.
A touchscreen includes an array of touch switches on a display. A touch switch is the simplest kind of tactile sensor. ... allowing for more flexible design. For ...
A sensor array is a group of sensors, usually deployed in a certain geometry pattern, used for collecting and processing electromagnetic or acoustic signals. The advantage of using a sensor array over using a single sensor lies in the fact that an array adds new dimensions to the observation, helping to estimate more parameters and improve the estimation performance.
In the 1960s, Paul Bach-y-Rita developed a vision substitution system using a 20x20 array of metal rods that could be raised and lowered, producing tactile "dots" analogous to the pixels of a screen. People sitting in a chair equipped with this device could identify pictures from the pattern of dots poked into their backs.
Current robotic and prosthetic hands receive far less tactile information than the human hand. Recent research has developed a tactile sensor array that mimics the mechanical properties and touch receptors of human fingertips. [38] [39] The sensor array is constructed as a rigid core surrounded by conductive fluid contained by an elastomeric ...
