Inspired by the human heart, Penn Engineers design tear-resistant soft material
Glass fibers embedded in stretchy silicone.

Using a 3D printer, Penn Engineering researchers are able to precisely control the alignment of glass fibers embedded within this stretchy silicone. The stripes represent regions with different fiber alignment patterns, and thus different levels of resistance to the tear making its way across the sample. (Image: Penn Engineering Today)

Inspired by the human heart, Penn Engineers design tear-resistant soft material

Engineers have designed a soft material for robotics, medical devices, and wearable technologies that are both tear-resistant and able to resist deformation.

Deconstructing the mechanics of bone marrow disease

Acollaborative team developed an alginate-based hydrogel system that mimics the viscoelasticity of the natural extracellular matrix in bone marrow. By tweaking the balance between elastic and viscous properties in these artificial ECMs, they could recapitulate the viscoelasticity of healthy and scarred fibrotic bone marrow, and study the effects on human monocytes placed into these artificial ECMs. (Image: Adam Graham/Harvard CNS/Wyss Institute at Harvard University)

Deconstructing the mechanics of bone marrow disease

A new understanding of how mechanical features of bone marrow affect resident immune cells in a fibrotic cancer points to future therapeutic strategies for cancers and fibrotic diseases.

Members of The Philadelphia Orchestra, including Carol Jantsch, principal tuba player, took part in a study led by Penn scientists Paulo Arratia and Douglas Jerolmack. Their investigation examined the aerosols professional musicians generate as they play. (Image: Courtesy of Paulo Arratia)

Music-making and the flow of aerosols

If simply breathing can spread the SARS-CoV-2 virus to others nearby, what about blowing into a tuba? Researchers from the School of Engineering the School of Arts & Sciences used fluid mechanics to study the movement of aerosols generated by musicians.

Shapeshifting microrobots can brush and floss teeth
Graphic shows how nanoparticle-based microrobots can remove dental plaque from teeth with their motion and the activity of hydrogen peroxide (H2O2) to kill microbes

Shapeshifting microrobots can brush and floss teeth

In a proof-of-concept study, researchers from the School of Dental Medicine and School of Engineering and Applied Science shows that a hands-free system could effectively automate the treatment and removal of tooth-decay-causing bacteria and dental plaque.

Center for Engineering Mechanobiology 2.0: Developing ‘mechanointelligence’
Microscopic view of an individual cell illuminated in bright colors.

The dynamics governing mechanointelligence vary greatly along time- and length-scales, so detailed models of individual cells and their components are necessary to connect the effects of their physical environments to the downstream effects those forces have on biological processes.
