Bio-MEMS is an abbreviation for biomedical (or biological) microelectromechanical systems.Bio-MEMS is typically more focused on mechanical parts and microfabrication technologies made suitable for biological applications.

BioMEMS devices can typically be considered as having at least one feature’s dimension in the submicron to micron range (100 nm–200 mm), and other dimensions of up to several millimeters.

They may operate in vivo or in vitro (inside or outside a living system), and have self-contained or external power sources. They may be smart systems with integrated microprocessors, and operate as either an open-ended (sensor or actuator) system or a closed-loop system (autoregulation). They may be all encompassing devices, but more typically they are integrated with other components and perform one or more functions in a chain of operations connected by tubing or other conduits. Implanted devices may be part of a distributed system such as fiber optic sensors that provide continuous information via light from various parts of the body to a central medical device.

Among the advantages of biochip miniaturization are lower manufacturing costs, reproducibility, small sample size, and reagent use. Improved signal-tonoise ratio, improved response time, precise control of mixing, reacting, and
discarding of waste products, in-line or embedded detection methods, and high throughput are also advancges of miniaturized biochips. (Ref.)
