Functional analysis aims to decompose the main functions of a product, which can be large and complex, into more manageable subfunctions. Recently, interest in explicitly considering users during functional modeling has grown to enhance analysis completeness, but how this addresses some commonly reported challenges for novice engineers is not clear. This research proposes and assesses […]
A40: The Role of Skin Deformation in Radial Pulse Measurements
Measured at the terminal region of the wrist, radial pulses provide crucial health information. They have long been used to diagnosis internal diseases in Eastern Medicine. In recent years, wearable healthcare devices (such as wrist worn braces and smart watches) use radial pulses to track the wearer’s activities and vital signs. Thus, accurate measurements of […]
A18: Documenting How Mechanical Engineering Students Understand Shear and Moment in Statics
Problem solving is integral to the engineering field. A significant piece of building strong problem-solving skills is having the correct understanding of fundamental engineering concepts. However, students may struggle to make the correct connections between different concepts when first learning material. Additionally, faculty may fail to identify which parts of the material students are not […]
C43: Characterization of Magnetorheological Elastomers under Tensile Loading
Tensile testing on artificial skin is being proposed to ultimately help develop a wearable device that can constantly and accurately monitor blood pressure for individuals at a high risk for cardiac related illnesses. The expected outcome is that a range of compositions of artificial skin will be determined that most accurately mimic the same range […]
C05-T: Challenges and Strategies in Remote Design Collaboration during a Pandemic
The COVID-19 pandemic forced college education to shift from face-to-face to online instruction. This effort is particularly challenging for freshmen and sophomore students, in engineering design projects where collaboration is needed. The study aims to qualitatively understand challenges and possible strategies in remote design collaboration through the lens of an undergraduate-level engineering design introduction class. […]
B18-P: Evaluating Mechanical Properties of MRE Artificial Arteries
Artificial arteries are made in a myriad of ways and have just as many uses within the medical field. The focus of this research is to vary the amount of iron content along with the magnitude of the applied magnetic field to alter the sample’s mechanical properties such that they accurately represent arteries within people […]
C24-P: 4D-Printing of Complex Ceramic Structure via Controlling ZrO2 Contents
Despite the fact that 3D printing has been developed for tens of decades, problems still exist when it comes to fabricate overhang structures or other complicated structures. To reduce this problem, researchers have made attempts on introducing novel concepts into 3D printing. Four-dimensional (4D) printing is one of these attempts and it has been successfully […]
B12-T: Fabrication and Characterization of Artificial Skins to Represent a Range of Human Skin Properties
Accurate measurements of blood pressure, a major indicator of multiple health risks, and its continuous monitoring are extremely important for personal health care. Invasive methods, which are unpractical for daily use, are the most accurate way to measure blood pressure (BP). Thus, there is a growing need for more accurate and convenient non-invasive measurement wearables […]
B31: Simulating Human Blood Pressure Waveforms Using a Hybrid Pulsatile System
Blood pressure is a major indicator of multiple health risks. There is a growing need for accurate non-invasive blood pressure (BP) measurement wearables that allow the users to monitor their BP continuously. However, current wearable technology doesn’t provide accurate BP readings, and it needs to improve the sensor technology embedded in wearables by considering various […]
