Scientists develop ‘self-powered tactile sensors for robotics and wearables’

by

Scientists at the Chung-Ang University in South Korea say they have developed “self-powered tactile sensors” for robotics and wearables, adding that they have also uncovered “advanced manufacturing strategies” for piezoelectric and triboelectric tactile sensors.

Piezoelectric and triboelectric tactile sensors, crucial for applications in robotics and wearable devices, face challenges in flexibility and environmental resilience.

In a new study, researchers have developed innovative manufacturing strategies to enhance sensor performance by optimizing material properties and fabrication techniques. [Read more…] about Scientists develop ‘self-powered tactile sensors for robotics and wearables’

Artificial skin brings robots closer to ‘touching’ human lives

by

Modern-day robots are often required to interact with humans intelligently and efficiently, which can be enabled by providing them the ability to perceive touch.

However, previous attempts at mimicking human skin have involved bulky and complex electronics, wiring, and a risk of damage.

In a recent study, researchers from Japan sidestep these difficulties by constructing a 3D vision-guided artificial skin that enables tactile sensing with high performance, opening doors to innumerable applications in medicine, healthcare, and industry.

SICK launches new product for contactless measurement of speed and length

by

SICK Sensor Intelligence has launched a new system for contactless measurement of speed and length.

With the SPEETEC sensor solution, SICK says it is expanding its product range for speed and length measurement of objects moving in a linear path to include technology that measures directly on the material surface.

The non-contact sensor is able to measure a wide range of web and continuous materials, as well as blanks with an accuracy of just 4 µm. [Read more…] about SICK launches new product for contactless measurement of speed and length

Columbia engineers develop ‘tactile robot finger with no blind spots’

by

Researchers at Columbia Engineering say they have developed a new type of robotic finger with a sense of touch. Their finger can localize touch with very high precision – less than 1 mm – over a large, multicurved surface, much like its human counterpart. (See video below.)

Matei Ciocarlie, associate professor in the departments of mechanical engineering and computer science, says: “There has long been a gap between standalone tactile sensors and fully integrated tactile fingers–tactile sensing is still far from ubiquitous in robotic manipulation.”

Ciocarlie led this work in collaboration with Electrical Engineering Professor Ioannis Kymissis. [Read more…] about Columbia engineers develop ‘tactile robot finger with no blind spots’
