Summary
Researchers developed a novel coral-like material for electronic skin, achieving dual terahertz (THz) and infrared (IR) stealth. This innovation enhances autonomous perception and electromagnetic protection in dynamic environments.
Area of Science:
- Materials Science
- Electromagnetics

Background:
- Electronic skin requires dual stealth for autonomous systems in complex electromagnetic environments.
- Integrating terahertz (THz) and infrared (IR) stealth technologies is challenging due to conflicting properties.
Purpose of the Study:
- To develop a novel composite material for electronic skin with compatible THz and IR stealth functionalities.
- To create a coral-like multi-scale composite foam (CMSF) inspired by natural coral structures.
Main Methods:
- Fabrication of a coral-like multi-scale composite foam (CMSF).
- Incorporation of conductive networks, heat insulation, metal particles, and magneto-optical materials.
- Characterization of THz reflection loss and IR emission properties.
Main Results:
- The CMSF achieved a maximum terahertz reflection loss of 84.8 dB.
- Demonstrated effective infrared stealth across varying temperatures.
- The electronic skin exhibited high sensitivity and reliability for environmental sensing.
Conclusions:
- The proposed CMSF successfully reconciles THz and IR stealth requirements for electronic skin.
- This material offers a unique combination of multispectral stealth and sensing capabilities.
- Potential applications include advanced camouflage and smart wearable devices.

01:33Somatosensation
37.0K
The somatosensory system relays sensory information from the skin, mucous membranes, limbs, and joints. Somatosensation is more familiarly known as the sense of touch. A typical somatosensory pathway includes three types of long neurons: primary, secondary, and tertiary. Primary neurons have cell bodies located near the spinal cord in groups of neurons called dorsal root ganglia. The sensory neurons of ganglia innervate designated areas of skin called dermatomes.

01:43Thermosensation
29.7K
Peripheral thermosensation is the perception of external temperature. A change in temperature (on the surface of the skin and other tissues) is detected by a family of temperature-sensitive ion channels called Transient Receptor Potential, or TRP, receptors. These receptors are located on free nerve endings. Those detecting cold temperatures are closer to the surface of the skin than the nerve endings detecting warmth. These thermoTRP channels, while temperature selective, have relatively...

01:03IR Frequency Region: Fingerprint Region
2.1K
IR spectra are divided into two main regions: the diagnostic region and the fingerprint region. The diagnostic region of the spectrum lies above 1500 cm−1. The absorptions resulting from single-bond vibrations of the N–H, C–H, and O–H stretch at higher wavenumbers and appear on the left side of the spectrum. The stretching absorptions of the C≡C and C≡N occur between 2100–2300 cm−1. In contrast, those arising from stretching absorptions of the...

01:16Sensory Functions of the Skin
9.1K
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...

5.2K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

951
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...
