In this presentation, I will introduce two researches conducted in UBC MEMS Lab: Microfabricated microlens scanner and PDMS Microbial fuel cell.
Applying the principle of NIR Raman microscopy and the foundry microfabrication process, MetalMUMPs, we have developed the first 2D microlens scanner aimed for skin cancer diagnosis. The microlens is actuated by both electrocapacitive force in out-of-plan direction and external electromagnetic field for transverse scanning. This microlens scanner in comparison with the existing scanning microscopic systems focus on miniaturized design and convenience for routine clinical application.
A microbial fuel cell (MFC) can converts chemical energy stored in organic & inorganic substances to electricity. It has potential application for energize low-power consumption implantable microdevices. The challenge in miniaturization is to increase the power density within a limited electrode surface area. We have microfabricated the first polydimethylsiloxane (PDMS) MFC with embedded micropillar electrodes to enhance the electron harvesting. This MFC is biocatalyzed by microorganism, Saccharomyces cerevisiae, and converts electricity from glucose in human plasma.
