Design Example: Resistive Touchscreen

424
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...

Tactile and Chemical Senses

350
Tactile senses encompass touch, temperature, and pain, each mediated by specific receptors. Touch receptors detect mechanical energy or pressure against the skin. Sensory fibers from these receptors enter the spinal cord and relay information to the brain stem. Here, most fibers cross over to the opposite side of the brain. The touch information then moves to the thalamus, which projects a map of the body's surface onto the somatosensory areas of the parietal lobes in the cerebral cortex.

Background:

  • Tactile sensors are vital for robotics and medical diagnostics, demanding high precision and real-time feedback.
  • Existing compact sensors struggle to achieve wide force ranges, high resolution, and rapid response across multiple axes.

Purpose of the Study:

  • To develop a compact, multi-axis tactile sensor with broad force measurement range, high resolution, and fast response times.
  • To demonstrate the sensor's utility in applications like surface topography scanning and medical diagnosis.

Main Methods:

  • Integration of a Gallium Nitride (GaN)-based optochip with a fingerprint-patterned polydimethylsiloxane (PDMS) film.
  • Development of an opto-electro-mechanical sensing mechanism for force detection.
  • Characterization of sensor performance, including linearity, resolution, and response/recovery times.

Main Results:

  • Achieved a linear response for shear forces (±100 mN) and normal forces (0-200 mN).
  • Demonstrated high detection resolution (0.07 mN) and rapid response/recovery times (0.85 ms / 0.82 ms).
  • Successfully verified sensor performance in surface topography scanning and organ lesion assessment.

Conclusions:

  • The novel tactile sensor overcomes limitations of existing technologies, offering superior performance in a compact form factor.
  • The sensor shows significant potential for enhancing robotic perception and improving accuracy in medical diagnostic procedures.
