FLEXIBLE WIRELESS ECG MONITORING DEVICE

Electrocardiogram (ECG) test is used to detect life‐threatening cardiovascular diseases. It records the electrical activity of the heart and displays an electrocardiograph. Traditional ECG monitoring devices require skin preparations and wires. which make them uncomfortable. They are also not ideal for remote or continuous heart monitoring. A flexible, portable, and wireless ECG monitoring device was developed to solve these issues. The device consists of dry electrode sensors, a comfortable chest belt, and a flexible printed circuit board capable of processing and transmitting an ECG signal to a smartphone for display.

A SCREEN PRINTED SENSOR TO DETECT ESTROGEN LEVELS IN LIQUIDS

As technology advances, extended space travel becomes closer to reality than a dream. However, there are concerns over the effect space has on personal health. A wearable sensing system could be used to detect hormone levels of astronauts as they are completing space missions. Varied materials have been investigated to be used to develop an estrogen sensor that can be fabricated from a screen-printing process, and a sensor made from graphene and mesoporous carbon paste has been prototyped and tested. This investigation shows a working prototype device and analysis with conclusions regarding its implementation and further development recommendations.

SNOWMOBILE RIDER INDICATOR

The snowmobile rider indicator is a durable device mounted to a snowmobile or other off-road vehicle to improve trail safety. This device displays a member’s position in a group to other trail riders on a seven-segment display and includes a hazard and safety light in times of distress. The light will flash the SOS sequence in Morse code.

SWEET MANUFACTURING ELECTRONIC STEERING

This project consists of the design of a tunable electronic steering system that interfaces with Sweet Manufacturing’s current use of torsion bars. The design is able to electronically adjust the gain of the input/output torque rather than swapping out physical torsion bars in the steering system.

VELOCITY ELECTRIC MOBILITY PLATFORM

The goal of this project is to help fill a gap in the micro-mobility sector by creating a competitive cloud-connected platform. The project shall design, build, and evaluate the basic motor control blocks for a first prototype of a micro-mobility device. This design includes a performance control module to drive a motor, GPS, and cellular connectivity for remote monitoring and the implementation of algorithms necessary for a comfortable user experience. The final intent is to have a unique embedded solution that can be optimally tuned and iterated on for future flexibility.

WMU SUNSEEKER TELEMETRY AND LIGHTING SYSTEM

The new Sunseeker solar car for 2021 requires a custom electrical unit that can provide wireless telemetry information, record CAN-based operational data, and control vehicle lights. Critical car telemetry information includes battery state-of-charge and cell voltages, various car temperatures, car speed, and both instantaneous solar energy and car energy consumption. This and other data is transmitted via a 900 MHz wireless signal while the vehicle is in motion, but also have the ability to transmit data over Bluetooth and/or Wi-Fi when the vehicle is stopped or charging. The unit also provides local non-volatile data storage for post-race download and a GPS device that can provide time and location information.

AUTOMATED DEFECT DETECTION FIXTURE

This project is an automated part inspection fixture that inspects parts from a manufacturing line for visible defects. To accomplish this, the fixture uses computer vision to analyze photographs of the part to search and detect defects. The defects are categorized and judged as to whether they meet acceptable criteria. Once the part is judged, it is returned to the manufacturing line to be outputted or scrapped and the data will be stored in a SQL server. Having an automated system will improve data traceability and production throughput by efficiently storing defect information.

AUTOMATIC SPEED-ADJUSTMENT TREADMILL

This project is to retrofit a treadmill with a motion-detecting sensor system along its side, which will monitor the user’s pace during use and adjust the treadmill belt speed accordingly. This enables the user to safely run on the treadmill with varying speed, without having to manually adjust its speed. With applications ranging from medical use to augmented reality, to everyday fitness, this treadmill upgrade can greatly increase usability for a low cost.

EEG Flexible Sensor

WMU researchers in the Center for Advanced Smart Sensors and Structures (CASSS) needed an electroencephalograph (EEG) sensor that could be worn for an extended period of time. The Flexible EEG Sensor is a 3D printable sensor that can read electroencephalographic waves without giving long-term use strain to the wearer. In addition to comfort, the EEG sensors must also be accurate and are benchmarked against commercially available ones.

Greenhouse Monitoring System

A greenhouse monitoring system (GHMS) was developed to maintain the required environmental variables. The GHMS maintains the temperature, light, and humidity through the use of a networked system of sensors under microprocessor control. The goal is to use a logical code sequence to monitor various interdependent variables in the greenhouse. The sensors in the module work in relation to each other to attain the best environmental conditions.
