2D Sensor Array

Definition

A 2D sensor array is a grid-like arrangement of multiple sensors that captures data in two dimensions, allowing for the measurement of tactile stimuli across a surface. These arrays are essential in creating more sophisticated haptic feedback and touch-sensitive devices, as they provide spatial information about contact points, pressure, and texture. By measuring variations in pressure or force at various points, they enable more nuanced interactions between users and machines.
