Optimization of hard–soft material interfaces: A 3D printed imitation of bone–tendon connections
Most people can relate to having a laptop charger break right where the flexible cable meets the solid adapter. This is just one example of how difficult it is to effectively interface hard and soft materials. Using a unique 3D printing process, TU Delft researchers produced hybrid multi-material interfaces that reached a remarkable closeness to nature's design of bone–tendon connections. Their research findings, recently published in Nature Communications, have numerous potential applications.
Despite the great difference in hardness between bones and tendons, their intersections in the human body never fail. It is this bone-tendon connection that inspired a team of researchers from the faculty of Mechanical, Maritime and Material Engineering (3mE) to explore ways to optimize the hard and soft interfaces of man-made materials.

Sexypink - Barbadian Artist | Annalee Davis on her Pray to Flowers – A Plot of Disalienation, my site-specific installation produced by the Sharjah Art Foundation for the SB15.“Pray to Flowers – A Plot of Disalienation, my site-specific installation produced by the Sharjah Art Foundation for the SB15 runs till June 11.
Barbadian Artist Annalee Davis working on one of her pieces in the exhibition
This post focuses on the attached interior space mirroring the densely layered garden.These embroidered panels acknowledge British sewing traditions Barbadian women inherited over centuries. Practiced across races & classes, their habitual utilization of the needle & thread instilled notions of what it meant to be feminine. Pre-approved imagery, stitches, & colours replicated across samplers trained middle- and upper-class women into becoming submissive housewives abiding by the church’s teachings & moral codes of respectability. Conversely, Pray to Flowers disregards the restricted range of carefully taught stitches, colour combinations, & sanctioned subject matter.
Rather, these works interweave crochet, applique, & embroidery addressing more indelicate discourse such as the impact of mono-crop farming & the plantation on today’s climate crisis. Amalgamating time-honoured stitches with fabricated ones, 100-year-old cutwork embroidery intermingles with contemporary so-called ‘African’ print fabrics worn at Barbados’ Crop Over festival. Merging pale pink crochet pieces & machine-made lace, this mash-up of fabrics, threads, & traditions acknowledges the creolization inherent in the formation of post-independent Barbados.
Instead of producing decorative works for the living room or dressing tables, – prescribed domains of women – these tapestries link the plantation with the 6th extinction. Cyanotypes of local botanicals growing in my garden acknowledge native flora rather than bluebells and cockleshells found in the embroidered tablecloths of my mother’s generation, fashioned on prescribed patterns they were fabricated. Satin-stitched phrases” advocate the worship of flowers, and our need to unlearn the plantation & defend nature.”- Annalee Davis

New material provides breakthrough in 'softbotics'
Carnegie Mellon University engineers have developed a soft material with metal-like conductivity and self-healing properties that is the first to maintain enough electrical adhesion to support digital electronics and motors. This advance, published in Nature Electronics, marks a breakthrough in softbotics and the fields of robotics, electronics, and medicine.
At Carnegie Mellon University, softbotics represents a new generation of soft machines and robots manufactured by multi-functional materials that have integrated sensing, actuation, and intelligence.
The research team introduced the material, a liquid-metal filled organogel composite with high electrical conductivity, low stiffness, high stretchability, and self-healing properties in three applications:
damage-resistant snail-inspired robot
modular circuit to power a toy car
reconfigurable bioelectrode to measure muscle activity on different locations of the body
"This is the first soft material that can maintain a high-enough electrical adhesion to support digital electronics and power-hungry devices," said lead author Carmel Majidi, Professor of Mechanical Engineering. "We have demonstrated you can actually power motors with it."
