Class on a Chip

Class on a Chip Banner

    • The Class on a Chip System is a MEMS (Microelectromechanical Systems) based tool for demonstrating and teaching engineering, physics, and micro/nano concepts.
    • The MEMS devices include micro-motors that are 1 mm in diameter and are used to spin even small gears.
    • A digital microscope is used to image the motion.
    • The video can be viewed on a computer monitor, video projector, and over the internet.
    • Multi-devices are available on each chip allowing a variety of experiments and demonstrations to be conducted.
    • A lab manual is available for both high school and college use.
    • Remoter users can operate the System using LabVIEW controls and view the dynamic devices through streaming video.
    • The System is in use at a number of universities around the country and has been used in demonstrations for hundred of middle and high school students.
    • The work has been supported by National Science Foundation grants through CCLI, REU, and SBIR programs.

Dr. Dallas makes presentations on micro and nanotechnologies to students. These are leading edge components found in many commercial products (smart phones, gaming controllers, video display) and vivid examples of applied STEM. Dr. Dallas teaches and conducts research in the realm of micro-devices and nano-structured coatings. The devices include a micromotor that is about 1 mm in diameter and other micro-actuators that can heat up to ~600ºC and then cool off to room temperature nearly instantaneously.

Dr. Dallas' presentation includes power point slides, videos, and a live demonstration of dynamic microdevices. The length of the presentation can be adjusted to meet the time constraints of your class (30 – 60 minutes). The level of the presentation can be adjusted to accommodate grades K-16. Dr. Dallas will bring his own laptop and demonstration equipment. He can hook his computer to a video projector in the classroom or can bring his own. His demonstration equipment can be hooked to a SmartBoard, thereby allowing the students to use the touch-screen feature to control the microdevices.
