Abstract: Embodiments of the present disclosure are related to MEMS devices having a suspended membrane that are secured to and spaced apart from a substrate with a sealed cavity therebetween. The membrane includes openings with sidewalls that are closed by a dielectric material. In various embodiments, the cavity between the membrane and the substrate is formed by removing a sacrificial layer through the openings. In one or more embodiments, the openings in the membrane are closed by depositing the dielectric material on the sidewalls of the openings and the upper surface of the membrane.

Abstract: A miniature gas analyzer capable of detecting VOC gases in ambient air as well as sensing relative humidity and ambient temperature can be used to monitor indoor air quality. The VOC gas sensor is thermally controlled and can be tuned to detect a certain gas by programming an adjacent heater. An insulating air pocket formed below the sensor helps to maintain the VOC gas sensor at a desired temperature. A local temperature sensor may be integrated with each gas sensor to provide feedback control. The heater, local temperature sensor, gas sensor(s), relative humidity sensor, and ambient temperature sensor are in the form of patternable thin films integrated on a single microchip, e.g., an ASIC. The device can be incorporated into computer workstations, smart phones, clothing, or other wearable accessories to function as a personal air quality monitor that is smaller, more accurate, and less expensive than existing air quality sensors.

Abstract: A bio-fluid sensor is formed by depositing polyimide on a glass substrate. Gold and platinum are deposited on the polyimide and patterned to form fluid sensing electrodes, signal traces, and a temperature sensor. The fluid sensor is then fixed to a flexible tape and peeled off of the glass substrate.

Abstract: A microelectronic device capable of detecting multiple gas constituents in ambient air can be used to monitor air quality. The microelectronic air quality monitor includes a plurality of temperature-sensitive gas sensors tuned to detect different gas species. Each gas sensor is tuned by programming an adjacent heater. An insulating air pocket formed below the sensor helps to maintain the sensor at a desired temperature. A temperature sensor may also be integrated with each gas sensor to provide additional feedback control. The heater, temperature sensor, and gas sensors are in the form of patternable thin films integrated on a single microchip. The device can be incorporated into computer workstations, smart phones, clothing, or other wearable accessories to function as a personal air quality monitor that is smaller, more accurate, and less expensive than existing air quality sensors.
