Abstract: A micro-electro-mechanical system (MEMS) transducer including an enclosure defining an interior space and having an acoustic port formed through at least one side of the enclosure. The transducer further including a compliant member positioned within the interior space and acoustically coupled to the acoustic port, the compliant member being configured to vibrate in response to an acoustic input. A back plate is further positioned within the interior space, the back plate being positioned along one side of the compliant member in a fixed position. A filter is positioned between the compliant member and the acoustic port, and the filter includes a plurality of axially oriented pathways and a plurality of laterally oriented pathways which are acoustically interconnected and dimensioned to prevent passage of a particle from the acoustic port to the compliant member.

Abstract: Embodiments described herein are directed to a temperature measurement device that includes a sensor body configured to be placed on a skin of a user. The temperature measurement device can include a first section defining a first lower surface and having a first thickness, a second section defining a second lower surface and having a second thickness, and a channel separating the first lower surface from the second lower surface. The temperature measurement device can also include a first set of temperature sensors positioned across the first thickness, a second set of temperature sensors positioned across the second thickness, and a processor configured to estimate a tissue temperature of the user based on comparing temperature signals from the first set of temperature sensors with temperature signals from the second set of temperature sensors.

Abstract: A microphone assembly has an interconnect substrate and a microphone transducer coupled with the substrate. A lid overlies the microphone transducer. At least a portion of the lid is spaced from the substrate, defining an acoustic chamber for the microphone transducer. The lid can have a layer of discretized metal or other patterned conductor. The discretized layer of metal or other patterned conductor is configured to inhibit formation of eddy currents, as when exposed to electromagnetic radiation. The lid can be grounded. Microphone modules and electronic devices also are described.
