Edible Jumpers Powered by Shell Snapping

open access: yesAdvanced Materials Technologies, EarlyView.
This work demonstrates an entirely edible, centimeter‐scale jumper by instantly releasing elastic energy through shell snapping. It can jump up to 36 cm, comparable to previous non‐edible jumpers. Moreover, this jumper can be loaded with an edible latch to trigger the jumping upon humidity stimulus autonomously.

Omnidirectional and Multi‐Material In Situ 3D Printing Using Acoustic Levitation

open access: yesAdvanced Materials Technologies, EarlyView.
An acoustophoretic 3D fabrication system enabling omnidirectional, multi‐material in situ printing is presented via acoustic levitation. Utilizing a phased array of transducers (PAT), it generates acoustophoretic forces for levitating and transporting materials in mid‐air, allowing precise, contactless, and voxel‐by‐voxel printing onto complex ...
