Sensory Functions of the Skin

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...

Introduction to Special Senses

Introduction to Special Senses

Sensory receptors play an integral part in comprehending our external and internal environments. They receive diverse stimuli, converting them into the nervous system's electrochemical signals. This conversion occurs as the stimulus alters the sensory neuron's cell membrane potential, instigating the generation of an action potential. This action potential is subsequently transmitted to the central nervous system (CNS), which integrates with other sensory data or higher cognitive...

Somatosensation

Somatosensation

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.

Tactile and Chemical Senses

Tactile and Chemical Senses

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.

Introduction to Sensory Receptors

Introduction to Sensory Receptors

Sensory receptors are vital in our ability to perceive and interpret the world. Sensory receptors are specialized cells in the peripheral nervous system that respond to various stimuli and enable one to experience different sensations. Based on specific criteria, sensory receptors are classified into distinct types.
The first classification criterion is based on cell type, position, and function. Some receptor cells are neurons with free nerve endings, where their dendrites are embedded in the...

Background:

Elasmobranch fishes (sharks, skates, rays) possess electroreceptors for prey detection.
These receptors sense electric fields generated by prey's biomechanical activity.

Purpose of the Study:

To develop a soft artificial electroreceptor inspired by elasmobranchs.
To enable noncontact detection of nearby objects via electric field sensing.
To provide a novel sensory modality for spatial perception in humans.

Main Methods:

Development of a soft artificial electroreceptor.
Sensing electric fields generated by objects.
Translating detected electric field information into auditory signals.

Main Results:

The artificial electroreceptor successfully detects relative positions of nearby objects.
Spatial information is conveyed to the wearer through auditory feedback.
Demonstrated noncontact object detection capability.

Conclusions:

The artificial electroreceptor effectively mimics natural elasmobranch electroreception.
This technology offers a new method for spatial awareness and object localization.
Potential applications in sensory augmentation and human-computer interaction.
