Image of the Month: A Piercing Barb
Engineers from Rutgers used 4D printing to create tiny needles that mimic parasites with backward-facing barbs. The researchers hope this technology could replace hypodermic needles
Engineers from Rutgers University have developed tiny needles made using 4D printing that mimic parasites and could replace hypodermic needles. 4D printing makes use of smart materials that are programmed to change shape after being printed. The thin microneedles are minimally invasive and, according to the researchers, cause less pain than alternatives.
