BIO-MATERIALS Bio-materials are materials that are employed for biological purposes. They come under the category of ADVANCED MATERIALS i.e. materials that have high tech applications. According to the International Union of Pure and Applied Chemistry (IUPAC), a bio-material is one which is exploited in contact with living tissues, organisms, and/or micro-organisms. Bio-materials are not a separate class of materials. Rather, they are common materials - naturally occurring or synthetically manufactured - that are deemed suitable for use in living organisms in general and humans in particular. Polymers, metals and ceramics are all examples of common biomaterials that are used in day to day medical procedures without complications. Sometimes, naturally occurring proteins such as collagen are also used as bio-materials with slight modifications, if required. Bio-materials have lots of uses in the field of medicine. They can be used for purposes as simple as a stent in cardiovascular surgery or as complex as a pacemaker or …show more content…
More specifically, piezoelectric materials can produce a voltage upon application of stress. This process also works in the opposite direction and hence they can show distort if current passes through them. Used in contact alarms and microphones. • Shape Memory Alloys/Materials These materials are pseudo elastic i.e. they can vastly alter their shape by changes in temperature and upon application of minimal stress. They are used in fire alarm systems. • Magneto restrictive materials They change their shape upon change in magnetic field. • Electro luminescent materials These materials give out light when electric current is applied to them. • Chromogenic materials Chromogenic materials exhibit change in color when they exposed o temperature changes or electrical

- Biometra is a subsidiary of Scientific Materials (SciMat). They handle vascular medical devices and produce catheters with innovative vascular technologies. Depending on their positions, they manage product operations, train clinic practical, and develop a marketing strategy at Biometra.
• Physiology - Noun 1. The branch of biology that deals with the normal functions of living organisms and their parts. 2. The way in which a living organism or bodily part functions.
Plasticine is a malleable solid, that can be found in stores. If you apply force to plasticine, the plasticine deforms or changes shape. The results may vary due to the amount of force applied to the plasticine. Remain the same E.g: Gravity. The force that holds objects down.
Biotic factors are the living components of an ecosystem. Each biotic factor needs energy to do work and food for proper growth.
A biotic factor is anything that is classified as a living organism, and also makes up an ecosystem. These biotic factors also affect the other organisms in their ecosystem. In an ecosystem there are three types of parts to a biotic compound that make up a food chain and they are as follows. Producers, which convert natural energy into a food source for consumers. Then, there are consumers who
It is a mineralized connective tissue formed by osteoblasts. Osteoblasts deposit a matrix of collagen and also release calcium, magnesium and phosphate ions that chemically combine within the collagenous matrix into a crystalline mineral, known as bone mineral, in the form of HA. Therefore, bone tissue is a natural composite consisting of a collagenous matrix and a mineral phase. Therefore, it is necessary to develop new therapeutic materials with the same hybrid structure that combine the strength, stiffness and osteoconductivity of an inorganic component with the flexibility, toughness and resorbability of an organic phase.[13,14] As such, in recent years, researchers have concentrated on developing the polymer/ceramic nanocomposites, which have the advantages of both polymers (structural stability, strength, biocompatibility and desired shape) and ceramics, and are more similar to natural

Biofuels are fuels that are produced by a biological process. A biofuel is a mixture of organic substances that are used as fuel in an internal combustion engine. Derivative of biomass, organic matter originated in a biological process, spontaneous or provoked, usable as an energy source.
What is biohacking? Biohacking is an individual or a community that gets together to explore a combination of biology and technology. Hacking also has a bad connotation but that’s not exactly what biohacking means.
Many outside forces may bend a solid out of its original shape. The ability of a solid to return to its original form after
Electromagnets can turn electrical energy into motion. Likewise the converse is true: they can turn motion into electrical energy.
As of November 30th, 2017, 116,080 people formed the organ transplant waiting list. On average, twenty people on this list will die today. The number of people that need an organ transplant continues to grow; every ten minutes a new name is added to the list. According to the U.S. Department of Health & Human Services, “only 3 in 1,000 people die in a way that allows for organ donation” (“Organ Donation Statistics”). In order for a deceased person to give organs, the organs must still be alive to donate. Organ transplantation improved greatly over the last century, but with an insufficient amount of organs available, it limits breakthroughs. In essence, new methods need to replace the unavailable organs. These methods drastically improve the process of organ transplantation, and in the future, the overall humans well-being.
