The first is research focusing on best and effective ways to teaching and learning in STEM K-16. He is currently researching on best practices in learning Dynamics, a sophomore engineering core course. The second research focus of Dr. Mativo is energy harvesting in particular the design and use of flexible thermoelectric generators. His investigation is both for the high-tech and low tech applications. In addition to teaching courses such as energy systems, mechanics, mechatronics, and production, he investigates best ways to expand cutting edge technologies to the workforce.

Many studies and subsequent government regulation for the work place specify guidelines for the work environment for manufacturing type plants. In some instances, these typerecommendations are not followed and could result in injuries that are preventable. Prevented injuries reduce medical costs and improve production in a safe environment. Industrial information combined with review of the literature was used to arrive at solutions to the problem. Two problems were identified that affected operators of an assembly table. The problems were addressed by first studying their nature, reviewing the literature, and recommending solutions. The first recommendation was to incorporate a table height adjusting mechanism to meet government standards related to work in assembly tables. The second recommendation was to reduce glare on the control center, an...

Part of the course requirement is for students to form teams and work together to conceptualize and design a digital system that meets an identified need for existing conditions or anticipated futuristic technology. This paper presents student approach to the process of need identification, conceptualization, design, and optimization of a digital system in a term project setting. In conclusion, we discuss lessons learned from student logic design, creativity, and aspirations.

Mativo and Stienecker (2007) and Mativo (2009) encourage the learning of engineering to be both fun and educational. Why mechanical systems? Learning mechanical principles takes students beyond the hands-on experience into higher-order learning. Haik and Shahin (2011) discuss the engineering design processes, which include essential transferable skills. Mechanical systems, such as transportation systems, have such transferable skills as they are applied everywhere in daily routines for personal and industrial purposes. This article examines mechanical systems based on science, technology, engineering, and mathematics (STEM) standards based on the Georgia state engineering and technology program. This approach provides a model that integrates different subject areas toward a solution. The interdisciplinary approach is hoped to stimulate critical-thinki...

A mechatronics platform has strength through its ability to offer dynamic and flexible solutions. Engineers and educators are devising methods and means to capture and maintain student interests while providing them with a meaningful experiential learning. This article presents a mechatronics learning experience using everyday toy-like products such as Legos and wood yet delivering a lasting impact. This learning experience is based on mechanics and motor selection. The fundamentals of engineering design such as statics and dynamics are presented. Further, design needs in electrical, and teamwork issues are addressed. The strength of the study is seen through a challenge presented that requires student innovation towards solving such problems. Students are p...

Their rigid nature makes them undesirable for adaption to existing structures with confined areas; locations that may experience severe mechanical vibrations; operate in extremely high temperatures; and where rapid temperature drop exists. The TEDs become a constraint when incorporating them in designs with varying contours. A flexible TED design is therefore desired to enable adaption of the devices in more applications. One approach towards the development of a flexible energy harvesting device such as the TED is to develop a flexible thermoelement. Developing a flexible thermoelement is a multi-stage design process. The design has to account for efficiency, structural integrity, and flexibility. This paper addresses the flexibility aspect while future work will include structural integrity by addressing thermal and mechanical loading; and efficiency by addressing materials selection and segmentation to achieve the highest possible pow...

Research is conducted to develop compliant thermoelectric generators (TEGs) capable of converting thermal loads to power, while also supporting shear and vibratory loads. Mathematical structural, thermal, and power conversion models are developed. Topology optimization is employed to tailor the TEG design yield maximal power production while sustaining the applied shear and vibratory loads. As a specific example, results are presented for optimized TEG legs with a void volume fraction of 0.2 that achieve compliance shear displacement of 0.0636 (from a range of 0.0504 to 0.6079). In order to achieve the necessary compliance to support the load, the power reduction is reduced by 20% relative to similarly sized void free TEG legs.

The development process was initiated to enhance the Mechatronics and Robotics Program at Ohio Northern University (ONU) Technological Studies Department resulting in development of an honors course. HONR 218-Animatronics was developed and offered in Winter Quarter of 2003/04 academic year. Animatronics is the art of bringing inanimate objects to life through computer technology, cable control, remote control or hand puppetry 1. Unlike biomimetics, animatronics is not purely based on various technologies and art is an important component because of the imitation factor leading to creativity and problem solving skills. In a well-blended crossdisciplinary setting, animatronics encompasses a wide span of areas limited by diverse subjects such as biomechanics, controls, costuming or manufacturing processes.

In general, the curriculum requires students to take a materials course. Current practices in both metallic and nonmetallic materials fields have been either theoretical with very minimal practical application such as in Engineering programs or heavy on the practice oriented approach with very minimal theory as in Industrial Technology programs. Both theory and practice components are critical to the understanding and utilization of materials. A balanced combination of the two components in addition to utilization of software in material selection is highly recommended for the Industrial Technology Curriculum. Wood, as a material, will be used for illustration purposes. Any other material may be substituted as desired.
