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 ...
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.
A tactile pixel or tixel is the smallest measuring/transmitting element of a tactile matrix. Is a part of haptic technologies. Design of a tactile pixel consists of a switching transistor and a resistive touch sensor. The electrical connection to the transistors is provided through high-resolution vias. [1]
A tactile sensor. Machine touch is an area of machine perception where tactile information is processed by a machine or computer. Applications include tactile perception of surface properties and dexterity whereby tactile information can enable intelligent reflexes and interaction with the environment. [13] (This could possibly be done through ...
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]
A tactile sensor array may also consist of FBAR devices, and gravimetric or mass sensing can be based on FBAR resonators. [28] As discrete components FBAR technology based parts like basic resonators and filters are packaged in miniaturised/small form factor like wafer level packages. FBARs can also be integrated with power amplifiers (PA) or ...
Tactel (short for tactile element) - a single sensing point on a tactile sensor array Tactel (fiber) , a trademarked brand of synthetic fiber produced by Invista Topics referred to by the same term
The sensor arrays are based on many organic thin film transistors that are turned on one at a time and the current that flows through the sensor (electrical resistance-based) tells you how much pressure is being sensed. They have simultaneously measured pressure and temperature by using two separate arrays and laying one on top of another.
