Overview Transducers '03 continues a series of biennial conferences that have been the premier forum for reporting research results in microsensors, microactuators, MEMS, and microsystems. This conference will bring new important advances in materials and microfabrication processes; innovative designs for physical, chemical, and bio sensors and microactuators; applications areas such as optical MEMS, RF MEMS, and micro total analysis systems; interface electronics; and modeling and CAD tools. Transducers '03 will be held from June 8 - 12, 2003 in historic Boston, Massachusetts, where it began in 1981. All sessions will be held at the Boston Marriott Copley Place, which also will provide accommodations for attendees. An exciting program of social events for attendees and guests is being planned, taking advantage of the culture and history that Boston has to offer.
