Paper on Okara 3D Printing Published

Cheng Pau’s paper on 3D printing of okara was published. We demonstrated that okara, a soybean byproduct, can be 3D-printed without any additives. This is one unique way to upcycle food waste, potentially contributing to food sustainability. Many thanks to the co-authors, Prof. Takahashi (Tokyo Tech, Japan), Prof. Arai (Kanazawa U, Japan), and Prof. Lee (NTU, Singapore).

This work was also highlighted as a cover image of ACS Food Science and Technology. Congratulations to Cheng Pau and the team!

MicroTAS 2021 @ Palm Springs

Terry, Xiaolei, and Michinao (on behalf of the lab, highlighting Kento and Rahul’s works) presented in MicroTAS 2021. We had a great online experience.

Terry’s oral presentation was selected as one of the three runner-ups of the best talk award. This is an exceptional achievement. Congratulations Terry and the team, and many thanks to Yi-Chin!

Book Chapter on Design and Fabrication of Microfluidic Devices Published

A book chapter on design and fabrication of microfluidic devices is published. We discussed recent progress of fabrication of microfluidic devices with design thinking approach. Congratulations Terry leading another fantastic work, and thanks Yi-Chin for co-supervising!

Opinion on Translation of Organ-on-a-chip Platforms Published

An opinion article on the organ-on-a-chip platforms was published in Trends in Pharmacological Sciences (TIPS). This article discussed the recent advance in organ-on-a-chip platforms and their academia-to-industry translation. Terry led the efforts co-supervised by Yi-Chin and Shrike. Congratulations and thank you for the opportunity for this collaboration.

Paper on Liquid Metal Antenna Published

Kento’s paper on the liquid metal antenna on the ultra-deformable substrate was published. We developed a liquid-metal-based flexible antenna for tissue-interfaced biomedical applications. Coil-shape microchannels were 3D-printed on a thin elastomeric film and Galinstan (a low toxicity gallium alloy) was infused to achieve a wireless device. The fluidic antenna operates in response to near-field communication frequency (13.56 MHz) under extreme deformation, on wet tissue, or both. We believe the developed flexible antenna finds applications as an implantable and tissue-adhesive wireless platform. Congratulations, Kento, Wenshen, Terry, and the team! Thank you for the amazing collaboration, Professor Huang.

Paper on microstructures fabricated by PolyJet printer published

Sindhu’s paper on micromolds fabricated by Polyjet printer is published. The fidelity of Polyjet printing is known to be affected by reflow and spreading of photoresin. In this work, we studied the deviations in both lateral and vertical dimensions of the microstructures printed by PolyJet printers. Crucially, we found the effect on the height of the printed features is prominent when the width of the feature is narrow. This finding should be useful for the design and fabrication of microstructures using PolyJet printers, especially for the fabrication of the mold for microchannels. Congratulations, Sindhu, Pravien and the team!

Paper on 3D-PAD published

James’s paper on 3D paper-based analytical device (3D-PAD) is published. We developed a method to apply fused-deposition modeling 3D printing to integrate 3D features with cellulose-based paper-based fluidic platform. As a demonstration, we have shown such a device can enhance the containment of organic solvents in the paper, which would be difficult in paper-based devices fabricated via solid wax printing. Congratulations, James!
