Organ-on-Chip Devices Toward Applications in Drug Development and Screening
(The American Society of Mechanical Engineers (ASME), 2018)As a necessary pathway to man-made organs, organ-on-chips (OOC), which simulate the activities, mechanics, and physiological responses of real organs, have attracted plenty of attention over the past decade. As the maturity ... -
Low-Cost Thermal Shield for Rapid Diagnostic Tests Using Phase Change Materials
(The American Society of Mechanical Engineers (ASME), 2018)The shelf life of point-of-care and rapid diagnostic tests (POC-RDTs) is commonly compromised by abrupt temperature changes during storage, transportation, and use. This situation is especially relevant in tropical regions ... -
Design and Evaluation of a Mechanically Driven Artificial Speech Device
(The American Society of Mechanical Engineers (ASME), 2018)This paper presents the design of a mechanically driven artificial speech device to be used by laryngectomees as an affordable alternative to an electrolarynx (EL). Design objectives were based on feedback from potential ... -
The Effect of Different Sterilization Methods on Polypropylene Syringes
(The American Society of Mechanical Engineers (ASME), 2018)This presents the influence of gamma irradiation on Pharmacopeia specifications, mechanical and flow parameters of polypropylene (PP) syringes. There has been significant progress in the terminal sterilization of single-use, ... -
Numerical and Experimental Simulations of the Wireless Energy Transmission and Harvesting by a Camera Pill
(The American Society of Mechanical Engineers (ASME), 2018)This paper investigates the energy transmitted to and harvested by a camera pill traveling along the gastrointestinal (GI) tract. It focuses on the transmitted electromagnetic (EM) energy in the frequency range of 0.18 to ... -
The Role of Impulse, Tissue Stretching, and Tip Geometry for Tissue Penetration of Polymer Needles
(The American Society of Mechanical Engineers (ASME), 2018)Polymer needles for medical injections offer a range of opportunities like compatibility with magnetic resonance scanning and simultaneous delivery of more than one drug. However, the lower stiffness property of polymers ... -
Design of a Novel Three-Dimensional-Printed Two Degrees-of-Freedom Steerable Electrosurgical Grasper for Minimally Invasive Surgery
(The American Society of Mechanical Engineers (ASME), 2018)In current bipolar electrosurgical instruments, a high frequency electrical sinusoidal wave is passed through the patient's body from an active electrode to the return electrode to cut, coagulate, or desiccate tissues. ... -
Novel Miniature Tip Design for Enhancing Dexterity in Minimally Invasive Surgery
(The American Society of Mechanical Engineers (ASME), 2018)Even though technological advances have increased the application area of minimally invasive surgery (MIS), there are still hurdles to allow for widespread adoption for more complex procedures. The development of steerable ... -
Development and Testing of an External Fixation Coupling for a Damage Control Orthopedic System1
