    Caracterización de transductores de bajo costo para el registro de señales bioacústicas
    (2020) Muriel Martínez, Cristian David; Ugarte Macías, Juan Pablo
    The biological sounds emitted by the human body during its operation, such as the pulmonary, intestinal, articular and cardiac, provide an easy way to assess the physiology of an individual; however its detection, acquisition and processing is expensive due tothe high price of the equipment.In this project an economic alternative was implemented through the characterization of low-cost transdu-cers for the registration of bioacoustic signals; in this case, cardiac type. In this sense, stethoscope bells weredesigned and printed in 3D, adapted to the transducer as a means of amplification at low frequencies, in which the heart beat is found.System functionality was verified by performing heart beat measurements in a clinical setting. The results obtained were quantified and analyzed by algorithms, showing a better response in low frequency, with theuseofbellsasameansofamplificationintheacquisitionofcardiacsignals.

    Desarrollo de una prótesis transradial externa para miembro superior basada en impresión 3D
    (2020) Ríos Mesa, Andrés; Meneses Benavides, Gustavo
    Urrently 3D printing is contributing greatly to the manufacture of prostheses. Its use can reduce the cost of prosthetic fabrication and allows the sea to be more accessible to those who need it. 3D printing allows us to make designs that fit better to the needs of each patient, through 3D printing can replace the body image and simulate the movements of the hands mechanically, it is also possible to develop prototypes in which Electronic components can be implemented to achieve an electromechanical prosthesis.Currently being developed a prototype external transradial prosthesis for a superior limb is based on 3D printing that fits the needs of the patient, this prosthesis has been adapted to the normal movements of the hands of the mechanical form. Several designs will be made in order to see the prototypes according to the needs and desires of the user. Through 3D printing we can manufacture prostheses that are modular, lightweight and comfortable enough, as well as low cost and manufacturing time. 3D printing is a technology that is advancing more and more and this is a more suitable solution for people who have a higher or lower type of disability

    Fabricación de joyería con nuevas tecnologías y materiales ecoamigables
    (Universidad de San Buenaventura - Cali, 2016-11) Araque Lizarazo, Ángela María; Dussán Aguirre, Rosmery
    This project has as objective the creation of contemporary jewelry pieces that helps reducing the environmental impact done by the illegal mining and the gold extraction industry. Since early times the use of accessories have been a way of expression used by the human being, for that reason we are looking for an alternative so people can still use accessories without harming our planet to achieve it. Gold extraction is an environmental and social problematic that not only affect the towns near the extraction point, it also affects all the Colombians citizens. The misuse and illegal dumping of highly toxic chemical substances in the rivers, Big area deforestation and work exploitation are just some of the problems that Illegal and legal Mining cause. For the fabrication of the pieces we turn to a new technology that have been in development, 3D printing which allow us to use an ecofriendly and biodegradable filament. Thanks to this the fabrication process is clean and sustainable.
