Glove-based air guitar that measures distance, pressure, and flex of finger movement to both simulate left-hand fret action and right hand strumming action. Basic features include on-off strumming detection, limited chord detection, audio output (preferably Bluetooth), data transfer from sensors through microcontroller of choice, calibration UI, mechanical resistance on fingers, and power for device. Advanced features, if time permits, are haptic vibrational feedback, accelerometer for sliding and hammer-on, multiple left-hand positions, and recording of snippets. The guitar will be stylized, meant for recreation and as a novelty.

This project has a significant hardware component (sensors, potential vibrational feedback, gyroscope, accelerometer, Bluetooth), mechanical touch (glove design), and software design (calibiration UI, sound samples, audio interpretation). It has a niche use for many music enthusiasts and guitarists. Not only is our idea helpful for basic practicing and learning, it will be fun to use and can be expanded for more professional and practical application.

There are similar products on the market that rely more on software or VR to simulate guitar playing, but our project will not be dependent on software for use (apart from calibration). The product will be able to function with just Bluetooth headphones. Another similar project was a haptic violin, but this also simulates bowing, and does not have that feature. Our guitar will hopefully be able to do the vast majority of things guitarists do (strum, pluck, slide). Even if not fully implemented, the bones of the project will allow for easy expansion without having to drastically change the engineering design.

Recovery-Monitoring Knee Brace

Featured Project

Problem:

Thanks to modern technology, it is easy to encounter a wide variety of wearable fitness devices such as Fitbit and Apple Watch in the market. Such devices are designed for average consumers who wish to track their lifestyle by counting steps or measuring heartbeats. However, it is rare to find a product for the actual patients who require both the real-time monitoring of a wearable device and the hard protection of a brace.

Personally, one of our teammates ruptured his front knee ACL and received reconstruction surgery a few years ago. After ACL surgery, it is common to wear a knee brace for about two to three months for protection from outside impacts, fast recovery, and restriction of movement. For a patient who is situated in rehabilitation after surgery, knee protection is an imperative recovery stage, but is often overlooked. One cannot deny that such a brace is also cumbersome to put on in the first place.

--------

Solution:

Our group aims to make a wearable device for people who require a knee brace by adding a health monitoring system onto an existing knee brace. The fundamental purpose is to protect the knee, but by adding a monitoring system we want to provide data and a platform for both doctor and patients so they can easily check the current status/progress of the injury.

---------

Audience:

1) Average person with leg problems

2) Athletes with leg injuries

3) Elderly people with discomforts

-----------

Equipment:

Temperature sensors : perhaps in the form of electrodes, they will be used to measure the temperature of the swelling of the knee, which will indicate if recovery is going smoothly.

Pressure sensors : they will be calibrated such that a certain threshold of force must be applied by the brace to the leg. A snug fit is required for the brace to fulfill its job.

EMG circuit : we plan on constructing an EMG circuit based on op-amps, resistors, and capacitors. This will be the circuit that is intended for doctors, as it will detect muscle movement.

Development board: our main board will transmit the data from each of the sensors to a mobile interface via. Bluetooth. The user will be notified when the pressure sensors are not tight enough. For our purposes, the battery on the development will suffice, and we will not need additional dry cells.

The data will be transmitted to a mobile system, where it would also remind the user to wear the brace if taken off. To make sure the brace has a secure enough fit, pressure sensors will be calibrated to determine accordingly. We want to emphasize the hardware circuits that will be supplemented onto the leg brace.

We want to emphasize on the hardware circuit portion this brace contains. We have tested the temperature and pressure resistors on a breadboard by soldering them to resistors, and confirmed they work as intended by checking with a multimeter.
