W17: Applications and Implications


I just finish week #16 and #17 is up and I feel really tired, but I have to continue..... It's been a long and hard journey throughout these weeks. I've learn lots of cool new things through each assignments and the participants. So, as I did last week, this week i'll be working and focusing on my final project. This week assignmets I have to answer some questions about my final project.

This week assignmets are:

Group assignments:

Questions about my final proyect.

  1. What will it do?

  2. The idea is to design like desk lamp that will have the next functions:

    • Leds will iluminate an acrylic figure.
    • It's going to measure heart beats and SPO2 in the blood, through a Max30102 sensor.
    • The measures will display in a screen and also will be visualize from internet.
    • I'm using a push button to change the intensity of the leds.

  3. Who's done what beforehand?

  4. I did some research to check out who had a similar idea of desinging a lamp. And actually I found several examples, all very interesting and great designs. But i couldn't find a lamp with "medical purposes", I mean a device that is a lamp and has the option to take heart beat and SPO2 measurements.

    • 2.1. First example ➔ Oscar Velasquéz from Puebla, Mexico.
    • The lamps basic functions are to turn on and off manually, to change the lights brightness and to work on Eco mode which reacts to the environment. The has a system gesture sensor as an interface since touch-less gestures APDS-9960 are the new frontier in human machine interfaces. This sensor can recognize different gestures like passing your hand.

      Data from: Oscar Velasquéz

    • 2.2 Second example ➔ Marjo Leinonen from Oulu, Finland.
    • She made a LED lamp has capacitive touch buttons on plywood for dimming the light. This lamp can be used in living room or bed room for decoration and lightning. It has sensor that will adjust the brightness of the light depending on the intensity of the light in the room.

      Data from: Marjo Leinonen

    • 2.3 Third example ➔ Euny Lee from Seoul, South Korea.
    • Slow glass will help people focus on slow, thoughtful breathing to reduce stress and anxiety. For exhalations, the lower portion of the hour glass will get increasingly brighter as it seemingly pours out of the top. During inhalation, the light will dim in the lower portion and appearing to move upward as the top portion gets brighter until it is fully lit. The breathing glass is switched on and off by flipping it to the other side.

      Data from: Euny Lee

    • 2.4 Fourth example ➔ Elena Cardiel from Segovia, Spain.
    • The Fold Lamp is an interactive piece of furniture which is able to recognize the ambient light and the presence of the user. It can be used to personalize the light of small-medium spaces, illuminating just one part of the room without disturbing the rest of the people in that same room, improving the quality of the ambient and saving energy.

      Data from: Elena Cardiel

    • 2.5 Fifth example
    • The objective of the research is to develop an initial prototype of a wearable device for monitoring the health status of the elderly. The final result, measures of health parameters of older adults were obtained, involving cardiac frequency, oxygen saturation, temperature within normal ranges. As well as plane axes to identify falls and directions with GPS without any inconvenience. All stored and visualized in an loT platform with alerts linked to a mobile application.

      Data from: Students from UNITEC, Biomedical engineering

  5. What will you design?

  6. I will design several things:

    • A base that integrates an acrylic figure, a display oled and sensors (max30102 and HC-SR04).
    • An electronic circuit.
    • An acrylic figure.
  7. What materials and components will be used?

  8. Materials and components
    PLA Max30102 sensor
    Copper PCB SSD1306 Oled display
    Soldering tin RGB LED
    Dupont cables Push button
    Acrylic
  9. Where will they come from?

  10. I will get the materials from three different places. The places are:

    • C&D TecHNologia: In this place I will get most of the components.
    • Larach y Cía: This is a local hardware store, in here i'll buy the acrylic.
    • Amazon:I had to buy the led because they were out of stock in C&D TecHNologia.
  11. How much will they cost?

  12. In this part I will detail how much i'll invest. A few details:

    • The tables show prices and total in local currency (Lempiras L.) and dollars ($)
    • I use a rate conversion of L. 24.68. Meaning $1.00 = L. 24.68



  13. What parts and systems will be made?

  14. I will make the base that will support the components, which consist of two parts: top and inferior.

  15. What processes will be used?

  16. The processes i'm using are:

    • 3D printer to make the base, both parts: top and inferior.
    • Electronic design for the circuit.
    • Embedded programming to program the sensors.
    • Computer controlled cutting for the acrylic figure.
    • Networking and communications (MQTT) to visualize the results in a web dashboard.
  17. What questions need to be answered?

    • How i'm going to integrate the components in the design?
    • How will I integrate the code in one program?
    • What communication protocol will I use?
  18. How will it be evaluated?

  19. The project will be evaluated if:

    • Max30102 sensor will measure heart beats and SPO2.
    • Results will display in a Oled screen.
    • Measurements can be visualiza via internet in real time.
