Abstract
An ambient sensing device is described especially suited to the sensing of a variety of ambient parameters. Photolithographic techniques are used to pattern a multiplicity of sensitive layers on a single monolithic substrate taking into account the wide range of plastic, gelatinous and ceramic materials to be patterned and the problems of their cross-contamination when in contact.
