Animator, scientist partner to illustrate cover of Advanced Materials

Baltimore, MD | Posted on February 25th, 2010

Rietveld's work illustrates an article about chemomechanical actuators—grippers that open and close like a hand in response to chemical reactions. The paper is based on the research of lead author, doctoral student Jatinder Randhawa in the laboratory of David Gracias, associate professor of chemical and biomolecular engineering and faculty affiliate of the Institute for Nanobiotechnology. Randhawa conceptualized the illustration of his research for the journal cover.

Says Gracias, "Chemomechanical actuation is intellectually appealing since it is widely observed in nature, but chemomechanical actuation is relatively unexplored in human engineering where the dominant strategy to actuate structures is based on electromechanical actuation (i.e. with electrical signals). Here, microstructures open and close reversibly in response to chemical surface oxidation and reduction without the need for any wires or batteries."
