Design Example: Resistive Touchscreen

A device engineer plays a crucial role in designing user interfaces for mobile devices. One such interface is the resistive touchscreen, which fundamentally consists of two metallic layers: a flexible upper layer and a rigid lower layer, separated by a narrow gap. The high resistance between these two layers is a key characteristic of this design.
When a user touches the screen, the two layers make contact at a specific point known as the touchpoint. This contact reduces the resistance between...
Sensory Functions of the Skin01:16

Sensory Functions of the Skin

The skin is the largest organ of the human body and plays a crucial role in our sensory perception. It contains a vast network of sensory receptors that contribute to the skin's protective function by perceiving physical, biological, and environmental cues and generating relevant responses.
There are two main categories of receptors on the skin: capsulated and non-capsulated. The non-capsulated ones are mainly the pain receptors. The capsulated ones can be further categorized based on the...

This study introduces the first user-interactive electronic skin (e-skin) that visually displays applied pressure in real-time. This flexible sensor technology integrates displays for intuitive human-readable output, advancing human-computer interaction.

Area of Science:

  • Materials Science
  • Electrical Engineering
  • Human-Computer Interaction

Background:

  • Electronic skin (e-skin) typically focuses on sensor optimization, lacking direct human-readable output.
  • Previous e-skin research has not explored user interfaces with visual feedback.

Purpose of the Study:

  • To develop the first user-interactive e-skin with integrated visual output.
  • To demonstrate a system-on-plastic with monolithic integration of multiple electronic components.

Main Methods:

  • Monolithic integration of thin-film transistor, pressure sensor, and organic light-emitting diode (OLED) arrays on a plastic substrate.
  • Development of an active-matrix OLED display for localized, pressure-quantified light emission.

Main Results:

  • The e-skin spatially maps applied pressure and provides instantaneous visual feedback via RGB pixels.
  • OLEDs activate locally upon touch, with light intensity correlating to pressure magnitude.
  • Successful system-on-plastic demonstration integrating multiple electronic components over large areas.

Conclusions:

  • This novel e-skin offers a direct, human-readable output for pressure sensing.
  • Potential applications include interactive devices, robotics, and health monitoring.
  • This work advances the integration of sensing and display technologies on flexible substrates.
