Potentiometer

2.8K
Voltage and current measurements using a standard voltmeter and ammeter alter the circuit being measured either by drawing or resisting the current flow, which introduces uncertainties in the measurements. Null measurements balance the voltages so that no current flows through the measuring device and, therefore, no alterations occur in the measured circuit.
Suppose the emf of a battery needs to be measured. If the battery is directly connected to a standard voltmeter, the measured quantity is...

Design Example: Resistive Touchscreen

949
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...

Field Effect Transistor01:29

Field Effect Transistor

1.8K
Field-effect transistors (FETs) are integral to electronic circuits and distinguished by their three-terminal setup: the gate, drain, and source. These transistors operate as unipolar devices, which utilize either electrons or holes as charge carriers, in contrast to bipolar transistors, which use both types of carriers. The primary function of the FET is to modulate the flow of these carriers from the source to the drain through a channel. The voltage difference between the gate and source...

Area of Science:

  • Materials Science
  • Electronics Engineering
  • Optoelectronics

Background:

  • Stretchable displays are crucial for advanced electronics like robotic skin and wearables.
  • Current stretchable color conversion layers (CCLs) face challenges with backlight leakage during deformation.
  • Heavy-metal-free quantum dots (QDs) are desirable for safer and more sustainable electronic components.

Purpose of the Study:

  • To develop intrinsically-stretchable and patternable heavy-metal-free quantum dot (QD) color conversion layers (CCLs).
  • To address the issue of backlight leakage in stretchable CCLs under mechanical stress.
  • To enable high-resolution, full-color stretchable micro-light-emitting diode (LED) displays for next-generation electronics.

Main Methods:

  • A versatile crosslinking technique was employed to load QDs into a polydimethylsiloxane (PDMS) matrix.
  • Uniform QD distribution and high concentration were achieved without compromising optical properties.
  • A fine-pixel patterning process compatible with the QD CCLs was developed.

Main Results:

  • The developed QD CCLs exhibited excellent color conversion with minimal backlight leakage, even under 50% tensile strain.
  • High QD loading was achieved in the elastomeric matrix, preserving optical performance.
  • The patterning process achieved resolutions up to 300 pixels per inch, suitable for high-resolution displays.

Conclusions:

  • This study presents a promising methodology for preparing stretchable QD/polymer composites.
  • The novel QD CCLs are suitable for high-resolution stretchable display applications, including robotic skin and wearable sensors.
  • The findings advance the development of flexible and wearable light-emitting devices without heavy metals.
