Use of forecasting haptic feedback to overcome distance limit in human-to-machine applications

Posted on by Haptic

A Tactile Internet is potentially the next phase of the Internet of Things, in which humans can touch and interact with remote or virtual objects while experiencing realistic haptic feedback. A team of researchers led by Elaine Wong at the University of Melbourne, Australia, developed a method for enhancing haptic feedback experiences in human-to-machine applications Read more about Use of forecasting haptic feedback to overcome distance limit in human-to-machine applications[…]

Design could enable new types of in-body sensors for biomedical research and treatments

Posted on by Haptic

For the first time, researchers have fabricated sensing elements known as fiber Bragg gratings inside optical fibers designed to dissolve completely inside the body. The bioresorbable fiber Bragg gratings could be used for in-body monitoring of bone fracture healing and for safer exploration of sensitive organs such as the brain. A fiber Bragg grating is Read more about Design could enable new types of in-body sensors for biomedical research and treatments[…]

Non-contact paint analysis

Posted on by Haptic

Many of today’s cars are coated with paint that exhibits a metallic or glittery shine. The exact sparkle and color you see is determined by the distribution and characteristics of tiny metal flakes used in the paint. A new approach based on the medical imaging technique optical coherence tomography (OCT) provides the car industry with Read more about Non-contact paint analysis[…]

Using polarimetric-thermal imaging for facial-recognition systems

Posted on by Haptic

Face recognition has become a key tool for unobtrusive human identification broadly applied in areas of surveillance, forensic, security, access control, etc. In recent years, although the accuracy of today’s visible-spectrum facial-recognition systems has rapidly increased and are robust to various conditions such as illumination, pose and expressions, there are some challenges that compromise the Read more about Using polarimetric-thermal imaging for facial-recognition systems[…]

Using Light to Create Sound

Posted on by Haptic

Researchers have developed a promising new fiber-optic based chemical sensing method that uses light inside a fiber to induce sound waves outside it, providing indirect information about what surrounds the fiber. By overcoming a significant limitation of existing sensors, the new method could improve sensing capabilities for a wide range of applications, including industrial processes Read more about Using Light to Create Sound[…]
