Abstract: A method is provided for the automatic control of cycling speed in a human. The method comprises: estimating the subject's actual cycling speed using one or more sensors to thereby obtain a measured speed; determining an error comprising a difference between a desired speed and the measured speed; and outputting, to the subject, a stimulus frequency signal wherein the stimulus frequency signal is based on the error in such a manner that when the subject pedals in a manner that matches a frequency of the stimulus frequency signal, the subject's actual speed controllably tracks the desired speed.

Abstract: Described herein are crosslinked alkylated poly(benzimidazole) and poly(imidazole) polymer materials and devices (e.g., fuel cells, water electrolyzers) including these polymer materials. The polymer materials can be prepared in a convenient manner, allowing for applications such as anion exchange membranes (AEMs). The membranes provide high anion conductivities over a wider range of operating conditions when compared to the analogous membranes that are not cross-linked. The crosslinked polymer materials have improved alkaline stability, when compared to the analogous non-crosslinked polymer materials.

Abstract: A new fabrication process for flexible and wearable microfluidic channel structures and devices is provided. Microfluidic channel structures and devices can be printed on textiles and in particular on flexible fabrics, such as clothing, for applications in wearable microfluidic sensors and systems. The wearable and flexible microfluidic devices are fabricated from water-insoluble plastisol polymers, which may be screen-printable, and sheets of paper may be used as a sacrificial substrate during production.

Abstract: A magnetic device comprising having a first magnetic layer having a first magnetization direction, a second magnetic layer having a second magnetization direction, a first coupling layer interposed between the first and second magnetic layers, a third magnetic layer having a third magnetization direction, a first magnetoresistive layer interposed between the third magnetic layer and the second magnetic layer, and a circuit connected to one or more of the layers of the magnetic device by at least a pair of leads. The circuit is configured to determine a change in resistance between the pair of leads. The change in resistance is based at least in part on a change in an angular relationship between the third magnetization direction and the second magnetization direction caused by an external magnetic field or a current passing through at least a portion of the device.

Abstract: The disclosed devices utilize nonlinearly coupled modes of vibration to provide robust inertial sensors, such as gyroscopes. This actuation mechanism introduces a wider bandwidth in the sense-mode frequency response curve, and consequently enhances robustness to parameter fluctuations due to operating conditions and fabrication imperfections. The vibratory modes of the device are designed to have distinct frequencies where the drive-mode natural frequency is twice the modal frequency of the sense mode. The nonlinear modal interaction due to internal resonance can also be magnified through nonlinearity feedback. The sense mode response can be enhanced in shape, quality factor, and bandwidth by feeding back nonlinear quadratic, cubic, etc. terms.
