Summary
Packaging material texture significantly impacts consumer perception. This study developed a system to objectively measure tactile properties like friction and roughness, correlating them with subjective human sensory responses.
Area of Science:
- Materials Science
- Sensory Science
- Tribology
Background:
- The tactile properties of packaging materials, such as films, wrapping paper, and cardboard, are crucial for the commercial success of food products.
- Previous research indicates that surface characteristics significantly influence subjective sensory responses.
- Key mechanical parameters influencing tactile feel include friction, roughness, compliance, and thermal properties.
Purpose of the Study:
- To design, construct, and utilize a multisensory measurement system for evaluating the tactile sensation of various packaging materials.
- To objectively quantify physical properties related to the 'feel' of packaging.
- To correlate objective measurements with subjective human perception.
Main Methods:
- An artificial fingertip equipped with sensors was used to interact with different packaging material samples.
- Experiments involved sliding and pressing the artificial fingertip against fixed samples on a force table.
- Objective measurements included surface roughness, friction coefficients, compliance, and temperature change rates.
Main Results:
- The multisensory system successfully acquired data on roughness, friction, compliance, and thermal properties of packaging materials.
- Forty volunteers provided subjective ratings of the packaging samples based on touch.
- Significant correlations were identified between the objective physical measurements and the volunteers' subjective tactile perceptions.
Conclusions:
- The developed multisensory system provides a reliable method for objectively assessing the tactile properties of packaging materials.
- Objective tactile measurements can effectively predict and explain subjective human sensory responses.
- This research offers valuable insights for optimizing packaging design to enhance consumer experience and commercial appeal.

01:27Tactile 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. This...
01:14Design Example: Resistive Touchscreen
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...

01:33Somatosensation
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.
01:11Sensory Perception: Organization of the Somatosensory System
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 stimulus...

01:16Sensory 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...

01:15Sensory Modalities
Sensation typically is the process by which the sensory receptors and sense organs detect stimuli from the internal and external environment and transmit this information to the central nervous system for processing.
General senses refer to the broad category of sensory information detected by receptors in the body and can be further grouped into somatic and visceral senses. Somatic sensations include touch, pressure, temperature, and pain and are essential for navigating our environment and...
