Feeling of a touch for robots through artificial intelligence and contact area patterns

Eight years ago, Ted Adelson’s research group at MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) unveiled a new sensor technology, called GelSight, that uses physical contact with an object to provide a remarkably detailed 3-D map of its surface.

Now, by mounting GelSight sensors on the grippers of robotic arms,...Read More »

All mighty friction shapes zebrafish embryos

A simple ball of cells is the starting point for humans – and zebrafish. At the end of embryonic development, however, a fish and a human look very different. The biochemical signals at play have been studied extensively. How mechanical forces on the other hand shape the embryo is the...Read More »

Tribology of cardiovascular devices: A brief review

According to American Heart Association’s 2017 Heart Disease and Stroke Statistics Update, nearly 801,000 deaths in the US had cardiovascular disease as the underlying cause of death. That’s about 1 of every 3 deaths in the US [1]. Cardiovascular devices are used to diagnose and treat heart disease...Read More »

Ocular Tribology

The word “ocular” refers to “related to eyes or vision”. Ocular tribology can be regarded as one of the application areas of biotribology where tribology is applied to solve tribological issues (friction, wear and lubrication) related to eyes. Let’s talk about two main areas related to ocular tribology,...Read More »

Tribological evaluation of condoms: A hypothesis

According to a WHO factsheet, an estimated 225 million women in developing countries would like to delay or stop child birth but are not using any contraceptive method. Contraceptive method apart from family planning can help in reducing the risk of sexually transmitted diseases as well as reducing...Read More »

Tribology and medical textiles: A brief outlook

In pharmacology, a drug is defined as a natural or synthetic substance other than food, used in treatment, cure, prevention, mitigation or diagnosis of a disease [1]. A drug can be taken by the patient in many forms such as by inhalation, injection, dissolving the drug under the...Read More »

Food Tribology

Tribology is the science of interacting surfaces in relative motion and of related subjects and practices. Earlier application of tribology was only limited to automotive industry but continuous research into field has opened new areas such as dental science, ocular science, orthopedics, sports and many more, where knowledge...Read More »

Superlubricity with Green Lubricant

Superlubricity is a state of vanishing sliding friction. It has been reported in glycerol/water mixture lubricated contacts, graphene-gold interface,  interface in presence of graphene and in other conditions. Increasing number of reports on superlubricity in macroscale is driven by the need of energy costs...Read More »


Brasenia schreberi mucilage - superlubric biological liquid

Superlubricity is a state of low friction, broadly defined as the state with the coefficient of friction lower than 0.01. This level is not achievable with classical lubrication mechanisms and currently other methods are being searched for. Existing methods of superlubricity require specific conditions, material combinations or limited to...Read More »

Reduced Friction: Inspired by Nature

Darvin’s theory of evolution is widely held concept which states that all the life has evolved from a common ancestor: fruits, animals, trees, flowers. During the gradual process of evolution, beneficial random genetic mutations in simple creatures accumulated and resulted in more complex species. The process of accumulation of only...Read More »
