HEART AND LUNG SOUND SENSING SHIRT
Abhiyash Nibber, Hesham Al Ramahi

PROBLEM
Millions of people across the world are affected by Heart and Lung illnesses but do not have access to quality healthcare. They often have to travel large distances to talk to a doctor and might have to meet several doctors in person before they can get proper treatment.

SOLUTION AND IMPLEMENTATION
We plan to build a shirt consisting of 10 MEMS microphones placed at different locations on the body. Each of these microphones will obtain the heart and lung sounds, which will be processed by a microcontroller and sent to the user’s phone via Bluetooth. To make sure that the user has sufficient mobility while having this shirt on, we will use stretchable cables to connect the microphones to the microcontroller. To power the shirt, we will use LiPo USB batteries which provide around 4.2 V at full charge. As far as amplification circuitry for the tiny biological signals is concerned, we will design a PCB for that and the op-amps will be powered by the LiPo with a boost converter that will provide us an effective 12V. The shirt is gonna be really tight as well, so if we "stick" the sensors in the shirt, it is unlikely they will fall out. data could then be sent to a doctor for analysis and save the patient’s time and money.

WHAT MAKES THIS UNIQUE ? There are shirts in the market that are able to detect a user’s heart rate and breathing rate but there is no shirt that detects the heart and lung sounds. The feature of recording the sound files and transferring it to a doctor is also very unique. This is different from Project 24 in Spring 2018 because we will implement a bluetooth feature for communicating with a smartphone, which the group wanted to but could not. Also, since this a shirt, we will also have to take sweating and stretchability into our mechanical design and wire up the suit using insulated stretchable wires such as the ones shown in the link here: https://mnwire.com/istretch/

Laser Harp MIDI Controller with Musical Articulations

Featured Project

Electronic music concerts usually need eye-catching visual aids to create a certain atmosphere. Laser musical instruments is a great way to do this. We have been thinking of this project for a while and it was ECE445 that made this laser harp come true. The novelty of this project is that the harp-like laser device mainly focuses on playing articulations with laser and sensors, as a true universal MIDI controller, to control timbres that are synthesized or sampled. Articulations include piano/forte, vibrato, tremolo, and portamento. With the help of Professors and TAs, we learned how to pick right the components, design PCB, soldering, and program microcontroller. Those skills are not only useful in this class but also really important to electrical engineers. Also, we learned how to use individual strengths, combined with effective teamwork, in the pursuit of meaningful goals.
