Summary
This study introduces a novel method for designing diabetic insoles to reduce foot pressure. Customized insoles increased foot contact area by 30% and decreased peak pressure by 35%, aiding diabetic foot prevention.
Area of Science:
- Biomechanics
- Materials Science
- Medical Engineering
Background:
- Diabetic foot is a severe diabetes complication linked to neuropathy and mechanical stress.
- Reducing foot-insole contact pressure is key to preventing diabetic foot incidence.
Purpose of the Study:
- To propose a new design method for optimizing insole stress distribution using functional gradient properties.
- To develop customized insoles that improve contact mechanics and reduce diabetic foot severity.
Main Methods:
- Utilized finite element analysis to study foot-insole contact mechanics.
- Correlated material moduli with structural porous unit properties for optimization.
- Employed additive manufacturing to create customized insoles for mechanical testing.
Main Results:
- The designed insole increased foot contact area by approximately 30%.
- Peak contact pressure was reduced by 35% with the new insole design.
- Demonstrated improved contact mechanics for customized insoles.
Conclusions:
- The proposed method effectively optimizes stress distribution in insoles.
- Customized insoles show significant potential in reducing diabetic foot severity.
- The methodology is adaptable for other material property optimization designs.

Structural proteins are a category of proteins responsible for functions ranging from cell shape and movement to providing support to major structures such as bones, cartilage, hair, and muscles. This group includes proteins such as collagen, actin, myosin, and keratin.
Collagen, the most abundant protein in mammals, is found throughout the body. In connective tissue, such as skin, ligaments, and tendons, it provides tensile strength and elasticity. In bones and teeth, it mineralizes to...

127.5K
Adenosine triphosphate, or ATP, is considered the primary energy source in cells. However, energy can also be stored in the electrochemical gradient of an ion across the plasma membrane, which is determined by two factors: its chemical and electrical gradients.
The chemical gradient relies on differences in the abundance of a substance on the outside versus the inside of a cell and flows from areas of high to low ion concentration. In contrast, the electrical gradient revolves around an...

25.1K
Fruits form from a mature flower ovary. As seeds develop from the ovules contained within, the ovary wall undergoes a series of complex changes to form fruit. In some fruits, such as soybeans, the ovary wall dries; in other fruits, such as grapes, it remains fleshy. In some cases, organs other than the ovary contribute to fruit formation; such fruits are called accessory fruits.

01:29Structure and Function of Erythrocytes
5.5K
There are between 4.2 and 6 million erythrocytes, also known as red blood cells, in every microliter of blood. These cells are small, flattened biconcave discs with centers that are depressed.
The erythrocyte plasma membrane is associated with proteins such as spectrin, which forms a flexible cytoplasmic meshwork. This meshwork allows erythrocytes to twist, turn, become cup-shaped, and regain their biconcave shape as they pass through narrow capillaries. Additionally, erythrocytes can form...

3.3K
The cell fragments known as platelets are disc-shaped, with an average diameter of about 3 μm and a thickness of roughly 1 μm. They play a crucial role in the body's vascular clotting system, which also involves plasma proteins, blood cells, and blood vessel tissues.
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000...
