BBW: Gen Alpha and Beyond

Creators: Winnie Liang

Designed a prototype for baby bottle warmers that can circulate the fluid in a more efficient manner by increasing the surface area to volume ratio that is exposed to heat, thus facilitating consistent and fast warming of the fluid without destroying its nutritional content. One of the key features of our prototype is ease of use, which is especially important for parents waking up in the middle of the night with a hungry crying baby. Furthermore, compared to the current bottle warmers available in the market which either require ten minutes to fully warm up or provide local hot spots, this prototype theoretically can warm up milk in as less as two minutes with an uniform temperature all throughout.

DIY Ovarian Health Tracker

Creators: Marianna Johnson

What if you could measure your hormones at home?

Right now, the only way to measure ovarian hormones is through doctor visits or expensive at-home tests. But turns out your body can measure ovarian hormones for you. Certain cells in your body change shape based on exposure to ovarian hormones (estrogen and progesterone).

We developed a cheap, reusable bioassay to dynamically measure circulating ovarian hormones by imaging these cells.

This product has a number of applications including learning your personal: ovarian health and ovulation, risk for certain hormone-related diseases, and interaction of behavior and hormones.

APIs, data and tools used: none

We built an obstacle detection system for the visually impaired. It is connected to ultrasonic sensors and has has an in-built alarm system which will sound an alarm with distance-variable intensity and periodicity. The parameters can be calibrated as desired. Potential scalability can include haptic sensors attached to the body for better spatial awareness (we were not able to implement it due to a lack of time).

Biofeedback or biotherapy

Creators: Jonathan Toomim

Biofeedback is a process by which a biophysical parameter of a person’s body is measured and feedback is given to that person to teach them how to control their own body. We examined HEG biofeedback, a process in which people learn control over their cerebral blood oxygenation. The question we asked was whether people learn how to control their blood oxygenation solely by getting feedback from the brain blood oxygenation measurement system, or whether detailed instructions of which mental state they should try to enter helped with the process.

Freedom of Decision-making

Creators: Siddhartha Datta

We learnt that your brain makes decisions about 200 milliseconds before you consciously decide to make a decision, and you are most likely to sway from it about 50 milliseconds before the decision.
We extrapolated a decision-making distribution of probability of sticking with an initial decision along time before conscious decision.
We used the distribution to run a Monte Carlo simulation of the AIDS epidemic, to see what would be the global outcome if people “thought twice” about fornication.

We have gambling intracranial ECoG readings – translation: epilepsy patients had electrodes stuck in their brains, and we asked them to show them a number, and if they think they can gamble to get a higher number and win money, they gamble, else they do not. We have 10 subjects with 200 trials each, with time series data of 5-69 electrodes.

Filtering upon median-level bets (i.e. remove forced/obvious choices), we trained a logistic regression to predict gamble or not-gamble, and used readings at different time-points to train, and plotted accuracy out. At 200ms before the decision is made, individuals are 70-80% likely to stick with the decision; at 50ms before, individuals are 30-40% likely to stick with the decision.

We extracted this probability distribution (likelihood to stick with decision vs time before conscious decision).

To apply the distribution, we considered the AIDS epidemic as a use case. CDC statistics show that about 22.9% of HIV transmission occurs via [heterosexual] fornication. As the disease is filtered to propagate via sexual transmission, the only probabilistic variable is likelihood to sway from decision.

To simulate this, we built a Monte Carlo simulation that propagates the AIDS epidemic from 1990 to 2016. We take the initial nodes at 1990; for each instance of sexual opportunity (assumed to randomly range from 52 weeks to 12 months per year), right before the decision is made, the user is given a 200 milliseconds counter, and during the counter the script runs coinflips to measure probability of continuing with the decision, and if the mean probability is to continue with the decision with significance level 1%, then fornication occurs and a new infected node is generated. Once a year is completed, the row is recorded. Given historical data on HIV infections and deaths, we were able to periodically remove dead nodes. This entire model resembles an SIR model (Susceptible, Infected, Removed).

The results are displayed via geographical visualization of each region and its AIDS count in terms of individuals, and how it changes over time.

Build a ~1m radio dish that will receive data from the GOES-16 weather satellite. GOES 16 is an NOAA satellite in geosynchronous orbit (stationary from the perspective of someone on Earth) that sends down a constant stream of high quality images of the Earth, as well as images of the Sun, and some other instruments. To receive the signal, we constructed a dish with a wire mesh and machined aluminum support structure. Afterwards we ran the signal through a filter and amplifier, to scan and decode the data. We were able to build the dish! ..but couldn’t find the signal.

Biodiversity thermometer

We created a colorful way to display the biodiversity of ants in US states. When a state is selected, lights display how many species of ants are native to that state. A single red light represents a range of 100-150 ant species. Orange is 151-200 ant species, yellow is 201-250, green is 251-200, and blue is the highest number of species at 301-350. For future directions, we hope that this device can be developed further so that it can query any species in any location. It will be useful for science enthusiasts to assess biodiversity wherever they are!
