A tactile sensor is a device that measures information arising from physical interaction with its environment. Tactile sensors are generally modeled after the biological sense of cutaneous touch which is capable of detecting stimuli resulting from mechanical stimulation, temperature, and pain (although pain sensing is not common in artificial ...
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.
Most practical SLAM tasks fall somewhere between these visual and tactile extremes. Sensor models divide broadly into landmark-based and raw-data approaches. Landmarks are uniquely identifiable objects in the world which location can be estimated by a sensor, such as Wi-Fi access points or radio beacons.
Array processing is a wide area of research in the field of signal processing that extends from the simplest form of 1 dimensional line arrays to 2 and 3 dimensional array geometries. Array structure can be defined as a set of sensors that are spatially separated, e.g. radio antenna and seismic arrays .
The word "tactile" means "related to the sense of touch" [1] or "that can be perceived by the touch; tangible". [2] Touch is incredibly important to human communication and learning, but increasingly, most of the content people interact with is purely visual. Tactile technology presents a way to use advances in technology and combined with touch.
A touchscreen includes an array of touch switches on a display. A touch switch is the simplest kind of tactile sensor. Types There are three types of switches called ...
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.
A tactile sensor array may also consist of FBAR devices, and gravimetric or mass sensing can be based on FBAR resonators. [29] 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 ...
