Abstract Widely accepted and deployed commodity consumer products (e.g., laptops, optical disk drives, flatbed scanners, tablets, personal digital assistants, cell phones, wrist watches) as well as high-performance components of consumer products (e.g., micromachined accelerometers, radiofrequency identification tags) present a prominent set of attractive capabilities for advanced sensors. For detection of chemical species in liquids and gases, we take advantage of previously developed, optimized, and mass-produced physical transducers, optoelectronic, radiofrequency identification, and other types of components and rationally combine them with sensing materials to produce new types of chemical sensors. This chapter presents several examples of our recent developments to demonstrate chemical sensors based on mechanical, radiant, and electrical signal-transduction methodologies. Keywords Micromachined accelerometers, Optical disk drives, Radiofrequency identification tags, Signal transduction
