Abstract
A digital strain encoder includes a gage-emitter, a sensor-receiver, a transmitter, and an energy source. The gage-emitter is affixable to a surface to be measured and deformable on a one-to-one basis with the surface, and emits a reference strain signal in the absence of strain and an altered strain signal when the surface is subjected to strain and the gage-emitter is deformed. The gage-emitter also emits a unique reference identification signal. The sensor-receiver floats over the gage-emitter so as not to deform with the surface, and detects the reference and altered strain signals and the identification signal emitted by the gage-emitter. The transmitter is coupled to the sensor-receiver for transmitting the detected reference and altered strain signals to a remote receiver.
