Capacitive Touch Sensor Designs, Substrates, and Stack-Ups

Capacitive touch sensors have revolutionized how we interact with technology, from smartphones and tablets to home appliances and automobiles. These sensors use the capacitance of an electric field to detect touch or proximity, offering a fast and reliable interface for users.

Stretchable Dual-Capacitor Multi-Sensor for Touch-Curvature

Differently from the conventional single-capacitor multi-functional sensors, our new multi-functional sensor is composed of two vertically-stacked capacitors (dual-capacitor). The unique dual-capacitor structure can detect the type and strength of external stimuli including curvature, pressure, strain, and touch with clear distinction, and it can also detect the surface-normal

Review of Capacitive Touchscreen Technologies: Overview,

The PSD can support multi-touch and high image clarity, but the larger-size touchscreens require higher computational power to extract the touch location. The FTIR also makes use of the TIR condition, but the touch location is attained from the lights escaped toward the opposite plane to the touched one as depicted in Figure 6b. Those lights are captured by

Introduction to Capacitive Touch Sensing

Thus, it is quite simple to create a capacitor using the conducting layers incorporated into a printed circuit board. For example, consider the following top view and side view representations of a PCB capacitor used

Advantages of A Capacitive Touch Screen. Using capacitive touch screens offers several advantages: Multi-touch Capability. One of the standout features of capacitive touchscreens is their ability to recognize multiple touch points simultaneously. This allows users to perform gestures like pinch-to-zoom and two-finger scrolling with ease.

Multi-touch — Part 2: Filtering and Touch Detection

After filtering, a 2D array of mutual capacitance measurements is ready for touch extraction. The simplest way would be using peak detection. In this scheme, the touch map is scanned, and then N highest peaks are remembered. But the node X-Y location are row and column indices, a rather coarse number.
