This paper presents a chip containing a flexible scaffold which facilitates the construction of tissues with different shapes. The chip, entirely made of Polydimethylsiloxane (PDMS), has 2 main components including actuator and channel layers. The actuator layer consists of a 6×6 array of membrane actuators, with round shapes. The channel layer has a single layered structure due to the simplicity...
This paper presents a flexible microscaffold driven by a thermal latch valve, which helps meet the necessity of engineered tissues with different structures for engineered organ assembly. Unlike the conventional approach, which normally utilizes a fixed scaffold, our flexible microscaffold offers many temporary scaffolds as needed. It consists of a 3×3 microactuator array with a diameter of 500 μm...
Assembling engineered tissues at the mesoscale into an engineered organ has specially attracted our attention since engineered organ usually has a very complex structure and cannot be fabricated simply by using a fixed scaffold. The fabrication of these composite tissues is, however, difficult since many different scaffolds are required. The flexible microsaffold, called “changeable cell culture (C...
