Harvard engineers have developed Mobilio, a smartphone app that uses AI, built-in sensors, and personalized audio beeps to give users with blindness or low vision continuous guidance and obstacle avoidance. Ph.D. student Raymond Liu led the research in collaboration with Patrick Slade, assistant professor of bioengineering at John A. Paulson School of Engineering and Applied Sciences and associate faculty member of the Kempner Institute. The Harvard Grid Accelerator supported the research.

A research team out of Kit Parker’s lab at the John A. Paulson School of Engineering and Applied Sciences has developed a way to create customizable synthetic blood vessel grafts in minutes using a focused rotary jet spinning technology. The research has the potential to make time-sensitive medical treatments faster and more personalized.

Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences built a device called a pico-calorimeter that directly measures heat signals from small groups of living cells. The device could lead to advances in bacterial growth monitoring or antibiotic resistance testing.

Harvard researchers have developed a 3D printing method that places “active” liquid crystal elastomers and “passive” elastomers side by side in filaments, effectively pre programming the filaments to bend, twist, expand, or contract in specific ways when heated or cooled.
