Microfabrication of Self-Oscillating Gel for Microdevices

Recently, microfabrication techniques, such as photolithography, are also attempted for preparation of microgels. Since any shape of gel can be created by these methods, application as a new manufacturing method for soft microactuator, microgel valve, gel display, and so on, is expected. Microfabrication of self-oscillating gel has also been attempted by photolithography for application to such microdevices [28, 29]. 

In these devices, possible application to DDSs is a self-oscillatory drug release microchip. If the microfabricated self-osciUating gel can be used as beating 

Microfabrication of self-oscillating gel has also been attempted by lithography for application to a ciliary motion actuator (artificial cilia) [30]. The gel membrane with microprojection array on the surface was fabricated by utilizing X-lay lithography (LIGA). With the propagation of chemical wave, the microprojection array exhibits dynamic rhythmic motion hke ciha. The actuator may also serve as a microconveyor.
