How AI inverse design and 4D printing are shaping mechanical metamaterials

by

Engineers are increasingly combining generative design algorithms with 4D printing to create mechanical metamaterials whose behavior is defined by geometry rather than chemistry. Instead of selecting a material and testing its limits, designers can now specify a target mechanical response and generate a microarchitecture to achieve it. One of the clearest demonstrations of this inverse … Read more

The surprising science of squeaky sneakers

by

It’s not just shoes that squeak when they slide over a hard surface. Bike brakes, rubber tyres, even some biomedical implants such as artificial hips have been known to squeal as soft and hard surfaces come into contact with each other. Read the paper: Squeaking at soft–rigid frictional interfaces So to better understand exactly what … Read more
