Abstract: A fluidic microelectromechanical system (MEMS) device includes fluid interaction elements (FIEs) that are configured to be monitored by a sensing device to generate an electrical signal in response to a fluid flow through the device. The FIEs include a serial arrangement of cantilevered lever arms to achieve increased sensitivity in a fluid flow sensor as compared to some conventional MEMS devices.

Abstract: A fuel cell membrane electrode assembly including a polymer electrolyte membrane (PEM) and first and second electrodes. The PEM is situated between the first and second electrodes. The first electrode includes a first catalyst material layer including a first catalyst material and having first and second surfaces. The first electrode includes first and second material layers adjacent to the first and second surfaces, respectively, of the first catalyst material. The first material layer faces away from the PEM and the second material layer faces the PEM. The first material layer comprises a graphene-based material layer having a number of defects configured to mitigate dissolution of the first catalyst material through the first material layer.

Abstract: A mobile communication device and associated control system is provided for determining a presence and location of pressure applied to the mobile communication device. The system can replace physical buttons on the mobile communication device. In embodiments, a sealed chamber, such as a tube, is filled with a pressure-transferring medium inside the sidewalls of the frame of the mobile communication device. Two (or more) pressure sensors can be mounted to the chamber to measure the pressure at two different locations in the chamber. In an embodiment, the time difference of the pressure wave arriving between the pressure sensors can indicate the location of the applied force. By knowing where the force is applied, a desired command from a user can be inferred.

Abstract: A fluidic microelectromechanical system (MEMS) device includes fluid interaction elements (FIEs) that can be displaced by an actuator to generate fluid flow. The FIEs include a serial arrangement of cantilevered lever arms to achieve, for example, high sound pressure levels in a micro speaker or high pump rates in a micropump as compared to some conventional MEMS devices.

Abstract: A transducer includes one or more actuator components configured to be encompassed by a cavity of a frame, wherein the one or more actuator components are configured to allow in-plane and out-of-plane movement with respect to the frame and configured to create haptic feedback in the in-plane or out-of-plane movement to the frame. The transducer also includes one or more sensing layers configured to detect changes of displacement in the frame, wherein the sensing layer is connected to the one or more actuator components.
