3. The purpose of this lab was to teach us how to write an algorithm for someone/something that
doesn't know how to do a task you want them to do. In this case, how to teach a robot how to walk.
Week 1: How to Walk Directions
Given: Robot knows how to stand up
Create instructions. Modify your list while talking to the group and note
those changes.
1. Starting from either side (left or right), lift your foot up by moving
your knee in the same leg the foot you want to move is close to
your chest by moving your knee up.
2. Make sure that your other foot stays in place at all times and
shift your weight on the leg that is staying in place.
3. From where your foot was initially when you were standing up,
move your foot in front of the spot where your foot was before
you lifted it up by straightening your leg.
4. Plant your foot in place in that new location and keep your foot
there, meaning that you do not move that leg now, and now you
can shift your weight onto that leg.
5. Repeat with the other side, and continue to do it, switching back
and forth between each side.
4. Week 2: An Introduction to Medical Imaging
The purpose of this lab is to understand how different types of
imaging works and apply how imaging works to create an
image.
(I want to share my favorite activity from this)
Background Information:
● Computed tomography - creates images through “slices”
● Attenuation - (opposite of amplification) reduce/make
smaller
● CT is 2D
Make “Views” or “Projections” for two locations of source and
detector. For both 1 and 2, assume that the objects completely
block the source.
1. Assume the source is on the left and the detector is on
the right
2. Then assume the source is on the top of the image and
the detector is on the bottom
● Highlight in some ways the area that two back
projections overlap each other
● This projection doesn’t account for the other dimensions
of the rectangles because you are only seeing it
horizontally and vertically, making the projections
inaccurate

We are trying to replicate:
5. Week 3: Ethics
There is a 20 year-old patient with endometriosis, causing significant pain. The
surgeon wants to perform surgery for it, but the patient wants a code status as
DNR/DNI, even though complication rate of this surgery is very low. The surgeon
finds it uncomfortable performing surgery without a CPR option. The patient
changes her mind.
?
What should the surgeon have done?
In this lab, we discussed four cases regarding ethical issues that can occur for biomedical engineers. As a
class, we determined what the right choice of action was for the person in care of the patient.
6. ● Most long-lasting and
lasts their entire life
● Durable - titanium
● Better for people
under 65
● Patient will most likely
be required to be on
blood-thinning
medication; blood
clots are common
● Clicking sound
● Older patients
● Costs: $20,000
● Risks of surgery,
bleeding, dying, etc.
● Last between 10 and
15 years: may
require another
replacement surgery
at some point.
● Often very effective for
treating damaged
aortic valves
● Less invasive than
other heart valve
procedures
● Cost: $23,000
● No need for long-term
medication
● Performed on patients
younger than 50
Week 4: Biomechanics
Mechanical Valve Biological Valve Ross Procedure
Help, I need a new heart valve!
Choice: Ross Procedure
7. Inequality of
access to hearing
devices; informed
consent of
parents
Hearing aids are
usually not covered
by insurance;
cochlear implants
are expensive
Hearing devices
are regulated by
FDA, FTC, and
FCC at gederal
level
Removes child from
support and culture
of deaf community
but not completely
included in the
hearing community
Week 5: Engineering in a societal Context
Ethical FinancialRegulatorySocietal
My group had to make a slideshow presentation about the ethical, financial, regulatory and societal factors
that impact the way assistive hearing devices are designed and made. I worked on the ethical slide, where I
discuss the inequality of access to hearing devices and the consent of the parents having an ethical impact
on how hearing devices are made.
8. Week 6: Instrumentation - Measuring Biological
Signals
60-100 bpm
Pulse oximeter
Chest strap heart
rate monitor
15-20 bpm
Wearable continuous
spirometer
Chest strap that
measures breath rate
Breath rate
120/80 mmHg
Automatic blood
pressure cuff
VENUS
Develop a system to measure heart
rate, breath rate, and blood pressure
at home. Assume values that deviate
by 25% are of concern
Heart Rate
9. Week 7: Photonics - Light and How We Measure it
Pathing of current goes from 9V battery (voltage) to
the photoresistor and then the LED
02
When exposed to light, photoresistor loses a lot
of its resistance
03
Replace the LED light with a ammeter to
determine the amount of current going through
04 Based on P=I2
R, as resistance (R) decreases,
current (T) increases, meaning that the
brightness (proportional to P) increases too
01
The goal of this lab was to build a simple electronic circuit that uses a photoresistor to measure light intensities. The
second activity was to figure out a way to use three light detectors to show what color light is being shown.
10. First slide of presentation
My group and I discussed the
way that gene editing will
impact society. We discussed
Monsanto soybeans and
CRISPR has ethical, financial,
regulatory, and societal issues
in society. This presentation
was an extension of Week 5.
Week 8: Final Class Presentation
