Methods and systems suitable for fabricating multi-layer elastic electronic devices, and elastic electronic devices formed thereby. A method of fabricating an elastomer-based electronic device includes printing a first liquid material and then a second liquid material on a fabric substrate that comprises fibers. The first and second liquid materials are sequentially printed with a three-dimensional printer that directly prints the first liquid material onto the fabric substrate so that the first liquid material wicks through some of the fibers of the fabric substrate and forms a solid matrix of an elastomer-based composite that comprises the matrix and the fabric substrate, after which the three-dimensional printer directly prints the second liquid material on the elastomer-based composite to form a film thereon. The elastomer-based composite and film are electrical components of the elastomer-based electronic device.

One example method involves generating a calibration control signal for controlling an actuator configured to rotate a first platform about an axis. The calibration control signal causes the actuator to rotate the first platform at least one complete rotation about the axis. The method also involves receiving encoder output signals. The encoder output signals are indicative of angular positions of the first platform about the axis about the axis. The method also involves receiving sensor output signals from an orientation sensor mounted on the first platform. The sensor output signals are indicative of a rate of change to an orientation of the orientation sensor. The method also involves determining calibration data based on given sensor output signals received from the orientation sensor during the at least one complete rotation. The calibration data is for mapping the encoder output signals to calibrated measurements of the angular positions of the first platform about the axis.

A multibend sensor is able to provide information regarding bending of the sensor data in a manner able to mitigate error propagation. A reference strip and a sliding strip are separated from each other by a spacer. Electrodes are located on the reference strip and the sliding strip. The bending of the multibend sensor will be reflected in the shifting of the sliding strip with respect to the reference strip and the measurements obtained from the electrodes. A finger may be operably connected to the reference strip, wherein the finger extends in the direction of the sliding strip, wherein movement of the reference strip with respect to the sliding strip is translated through the finger.

A method for detecting components of dielectric materials is disclosed. The method includes use of a sensor to obtain at least one of a strain-dielectric coefficient data series at multiple frequencies or a stress-dielectric coefficient data series at multiple frequencies and using a processor to analyze resulting data, when a strain field or a stress field is known. The method also includes use of a sensor to obtain rheo-dielectric coefficient data at single frequency or data series at multiple frequencies and using a processor to analyze resulting data, when shear rate is known. The resulting data is used to perform material process or operation monitoring and control, quality examination, and characterization. Systems for detecting components of dielectric materials and for dielectrostriction measurement are also disclosed.

According to the techniques herein, one or more sensors coupled to an aligner are used to sense one or more physical qualities of the aligner to determine whether the physical qualities indicate that the aligner material has relaxed and has, e.g., reduced the force systems applied to teeth and/or that the teeth movement for the stage has slowed down. The sensors may provide a signal that represents whether or not the physical qualities fall below a threshold value. A treatment plan may be modified if needed. These techniques have the potential to make treatment plans faster and more effective by speeding up some stages while making sure some, perhaps other, stages are implemented only after the teeth are near the appropriate position.
