Glove senses objects and attaches

cientists at Virginia Tech have developed a glove for
grasping things underwater with rubber suckers
and a sophisticated sensing capability that mimics
an octopus's unique muscular and nervous systems. The
octopus is well equipped to handle objects in the water,
facilitated by more than 2,000 suckers spread across eight
arms and an ability to process information from an array of
chemical and mechanical sensors.
In creating the " Octa-Glove, " the researchers sought to
recreate these capabilities for the human hand. The glove
features rubber stalks capped with soft, actuated membranes
that mimic the octopus suckers and are designed to adhere
to both flat and curved surfaces while only applying light
pressure. It does this with an array of micro-LIDAR optical
proximity sensors that detect nearby objects.
A microcontroller connects the sensors with the
synthetic suckers to govern their behavior, with the
gripping abilities of the glove able to be configured by
tuning the sensor array depending on the task at hand.
3D printed shoe adapts to the foot's ergonomics
I
n a reinterpretation of classic shoe design, German design studio Wertel Oberfell's
Auxetic Wear is a 3D printed shoe that uses an auxetic structure to adapt itself to
the ergonomics of its wearer's foot. Combining traditional shoemaking with modern
technology, the designers emulate techniques from classic craftsmanship to devise
a design that displays a stitched and glued pattern comprised of low-profile, twodimensional
shapes.
Made of thermoplastic polyurethane (TPU) with a Shore hardness of 98A, the
semi-flexible filament offers high tear and tensile strength, and the auxetic structure
expands bi-directionally as soon as a tensile force is applied. It expands or compresses
on a local level to take on each ergonomic form of the foot in each instance, enhancing
comfort through a distinct design. A skeleton-like base gives the shoe its final organic
form and serves as reinforcement to the auxetic structure. Photo: Wertel Oberfell.
