Biomimicry Wing Humidity Sensor

Leverage key learnings from how birds/flies/butterflies/insets' wings function on detecting humidity to unlock the myth for building a sustainable (longer lifespan) and accurate humidity sensor potentially through augmenting other physical parameters that's less subjective to dirt and other interference factors, potentially collaborate with Biomimicry Institute: https://biomimicry.org, as well as this other fantastic ...more »

MEMS oscillator to measure relative humidity

We propose the use of an electrostatic MEMS (Microelectromechanical system) oscillator exposed to air to measure relative humidity. As water content in air changes, this should change the MEMS air viscosity and its air’s dielectric constant. Because those changes are so small, we propose amplifying the sensor’s response by dynamically driving the sensor at its subharmonic regime (actuation at twice the natural frequency). ...more »

3D Print Airflow Sensor

Leveraging 3D printing for manufacturing personalized, highly flexible, precise and scalable airflow sensors to address the current manufacturing constraints of lab produced costly airflow sensor. It is strongly recommended to leverage the capability and resource at UI Lab here in Chicago Goose Island to make large scale 3D manufacturing feasible, desirable and viable.

Building Robotics Call for Innovation

Passive IR Motion Detector Sensor for MRT Measurement

I propose using Passive Infrared (PIR) sensors, similar to those used in motion detectors, to measure the infrared energy in a room and use correlations to convert this data into MRT values. PIR sensors of this type have several positive points to consider: • Wide detection angles; • Long detection range; • Inexpensive; • Rapid response; • Would be able to detect both absolute values and changes of the infrared ...more »

Wireless sensor network for agriculture applications

Most of the new agriculture technologies, such as precision agriculture and precision farming rely on installation of connected sensor systems. Many of those agricultural systems require cellular coverage to connect the agriculture sensors to the gateway. Because cellular coverage is not available everywhere, many farmers are unable to use advanced agriculture technology. Ironically as it may be, seems like agriculture ...more »
