Abstract:
A wearable device is provided having multiple sensors configured to detect and measure different parameters of interest. The wearable device includes at least one monolithic integrated multi-sensor (MIMS) device. The MIMS device comprises at least two sensors of different types formed on a common semiconductor substrate. For example, the MIMS device can comprise an indirect sensor and a direct sensor. The wearable device couples a first parameter to be measured directly to the direct sensor. Conversely, the wearable device can couple a second parameter to be measured to the indirect sensor indirectly. Other sensors can be added to the wearable device by stacking a sensor to the MIMS device or to another substrate coupled to the MIMS device.

In an electronic component with a component housing and an integrated circuit with sensor function which is accommodated in a plastic electronic housing, wherein the component housing has a cutaway in the region of the circuit with sensor function so that the integrated circuit can perform its function as a sensor through the cutaways, the component housing lies flush with the edge of the cutaway on the electronic housing and is joined in sealing manner with an adhesive bond to the electronic housing. The component housing has an approximately vertical section on the edge of the cutaways, which section extends along the side of the electronic housing. A horizontal section is also present and projects horizontally over the electronic housing.

According to an embodiment, a microelectromechanical systems (MEMS) transducer includes a substrate with a first cavity that passes through the substrate from a backside of the substrate. The MEMS transducer also includes a perforated first electrode plate overlying the first cavity on a topside of the substrate, a second electrode plate overlying the first cavity on the topside of the substrate and spaced apart from the perforated first electrode plate by a spacing region, and a gas sensitive material in the spacing region between the perforated first electrode plate and the second electrode plate. The gas sensitive material has an electrical property that is dependent on a concentration of a target gas.

Abstract:
A single silicon wafer micromachined thermal conduction sensor is described. The sensor consists of a heat transfer cavity with a flat bottom and an arbitrary plane shape, which is created in a silicon substrate. A heated resistor with a temperature dependence resistance is deposed on a thin film bridge, which is the top of the cavity. A heat sink is the flat bottom of the cavity and parallel to the bridge completely. The heat transfer from the heated resistor to the heat sink is modulated by the change of the thermal conductivity of the gas or gas mixture filled in the cavity. This change can be measured to determine the composition concentration of the gas mixture or the pressure of the air in a vacuum system.
