Bioengineering Final Documentation – ATeChToP

Bioengineering Project Final Documentation ATeChToP Project Manager: Monica Cabingatan Communications: Edward Diego Sensors, Actuators, and Power: Hector Medina MC3: Gianfranco Parreno     Objective Play is essential to optimal child development for the cognitive, physical, social, and emotional well-being of children and youth. Certain medical conditions prevent many children from playing and socializing to their maximum […]

Lilypad Microcontroller

Written by: Edward Diego (Communications) Approved by: Monica Cabingatan (Project Manager)   LilyPad Figure 1. The Arduino Lilypad with ATMEGA32U4 24.95$ Figure 2. General Specifications In order to use the Plessey PS2320B ECG sensor an Arduino Lilypad will be used to digitize the output of the sensor for transmission and processing.  To adapted to heart rate […]

Enabling Technology-Paperbot Modes

Written by: Edward Diego (Communications) Approved by: Monica Cabingatan (Project Manager)   Point of Care(POC)- The Paperbot Figure 1. AUTOCAD drawing of Paperbot There are many children whose condition(osteogenesis imperfecta, immunodeficiency, late stage cancer etc.)  forces them to be hospitalized or bedridden for long durations.  These children will have limited benefit from the WBAN sensor […]

Analog ECG Sensor

Written by: Edward Diego (Communications) Approved by: Monica Cabingatan (Project Manager)   Figure 1. PS25205B Dry surface ECG sensor from the EPIC series by Plessey Semiconductors The PS25205B is an ultra low power sensor by Plessey Semiconductors.  It is a solid state sensor, drawing its input straight from dry electrodes and outputing an amplified signal […]

Sensor Input Impedance

Written by: Edward Diego (Communications) Approved by: Monica Cabingatan (Project Manager)   The reason why electrocardiograms, or any other sensors that read electrical activity off the patient, must have a high input impedance is because the distribution of charge across to sources of resistance; the body/skin and the sensor itself.  For dry sensors, placed externally […]

Non-Invasive Glucometer (NGM)

Written by: Edward Diego (Communications) Approved by: Monica Cabingatan (Project Manager)   Frequent and accurate blood glucose measurements are essential to managing diabetes.  For our sensor suite, traditional glucometers cannot allow the full potential of the wireless body area network because they require the user to draw blood and wait for the results on a […]

Model Illustrations

By: Monica Cabingatan  (Project Manager)   This post demonstrates the process of illustrating the model of our project. Started as a scratch showing a happy kid playing, then putting our sensor suite on the following locations: Accelerometer- waist Pulse Oximeter- earlobe ECG- chest EMG- arm Temperature- neck       Ultimately, the model should represents our […]


Written by: Hector Medina (Sensors, Actuators, and Power) Approved by: Monica Cabingatan (Project Manager)   These are the ranges for current: A current of 0.25 mA on the body can cause a buzzing or tingling sensation. At 10mA the muscles contract. Therefore, the minimum current is 0.25mA, and the maximum current is 10mA. However, according […]
