Abstract
Devices, systems, and methods provide direct digitization and encoding of a parameter to be sensed or measured. Digitized readings are encoded into binary bits, which are acquired and handled by digital devices. An all-digital sensing device can be implemented in passive, active, or semi-passive forms, and in some embodiments includes a transducer, digitizer/encoder, reader, and transmitter. A transducer converts the parameter to be measured into a digitizable quantity, based on such as mechanical deformation, dielectric properties, or electromagnetic wave or acoustic-wave properties. A piezoelectric material transducer converts stress/pressure into resistance or voltage. A fiber-optic interferometer transducer converts pressure/temperature/PH into irradiation amplitude or wavelength shift in spectrum domain. Encoded binary or quasi-binary states are identified by a reader. Binary states have resolutions arranged according to a 2format. Each binary state can be presented in mechanical, electromagnetic, optical, or acoustic forms, or in step or continuous form.
