Summary
Understanding biobased composite perception is key for sustainable materials. Bimodal sensory evaluation reveals visual and tactile factors influencing perceptions of naturalness, beauty, and value.
Area of Science:
- Materials Science
- Sustainable Design
- Sensory Perception
Background:
- Biobased composites are sustainable alternatives to fossil-fuel materials.
- Large-scale adoption is limited by perceptual challenges.
- Understanding perception mechanisms is crucial for commercial success.
Purpose of the Study:
- To investigate the role of bimodal (visual and tactile) sensory evaluation in biobased composite perception.
- To identify key attributes and their correlations in material perception.
- To link sensory characteristics to perceived value and naturalness.
Main Methods:
- Utilized the Semantic Differential method for sensory evaluation.
- Employed bimodal (visual and tactile) assessments.
- Analyzed perceptual clusters based on sensory dominance.
Main Results:
- Biobased composites formed distinct perceptual clusters.
- Attributes like 'Natural', 'Beautiful', and 'Valuable' positively correlated, influenced by both visual and tactile cues.
- 'Complex', 'Interesting', and 'Unusual' attributes were visually dominated.
Conclusions:
- Identified perceptual relationships and components of beauty, naturalness, and value.
- Highlighted visual and tactile characteristics influencing these perceptions.
- Suggests material design leveraging these insights can enhance designer and consumer appeal for sustainable materials.

01:27Tactile and Chemical Senses
337
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.

01:11Sensory Perception: Organization of the Somatosensory System
3.2K
The somatosensory system is the central and peripheral nervous system component that senses and processes touch, pressure, pain, temperature, and body position or proprioception. The process of sensation takes place at three levels:
The receptor level:
The receptor level is the first stage of sensation. It involves the detection of a stimulus by specialized sensory receptors. The stimulus must arrive within the receptor's receptive field. Next, the receptor converts the energy of the...

1.1K
A composite body is a body made up of multiple parts, connected to form a larger, unified object. Each part has its own weight and center of gravity, which must be considered to determine the center of gravity of the composite body. In cases where the density or specific weight is constant, the center of gravity coincides with the centroid.

Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.
