Research

Recent progress in microelectromechanical systems (MEMS) is being applied to biomedical applications and has become a new field of research unto itself, known as BioMEMS. BioMEMS is an enabling technology for ever-greater functionality and cost reduction in smaller devices for improved medical diagnostics and therapies, based upon the same technology used for computer chips.

For example, BioMEMS technology can enhance catheter-based procedures by providing pressure sensing, imaging, drug delivery and tissue sampling, all via tiny biochips. On the nanoscale, BioMEMS can be used to engineer micro-/nanometer-sized features for tissue engineering, protein analyses, assays, and cell interrogation.

Areas of application under investigation include:

• Miniature high-performance ultrasonic transducers, which integrate electronics and piezoelectric transducers on a single chip to create high-quality ultrasonic images.
• An implantable artificial kidney using Silicon Nanoporous Membranes.
• Biochips for cell detection and manipulation.
• Surface textures and systems to enhance tissue engineering of bioartificial tissues and organs.
• The design and development of miniature in situ sensors for pressure, temperature strain and flow for minimally invasive and noninvasive surgical procedures and post-surgical follow-up.
