It is difficult and inconvenient to manage the regular infusion of insulin in a dog with diabetes. Diabetic dogs require insulin shots every time they have a meal. This is often twice a day. It requires measuring insulin into a syringe, injecting, and disposing of sharps. This is a wasteful process that is also very time intensive. Additionally, the dog may not respond well to needles.

Solution Overview:

Our solution is a system composed of software and hardware. The hardware component is a wearable insulin pump. This pump connects to an accompanying smartphone app over Bluetooth which allows the owner to dispense insulin doses when desired. The device will also be battery powered and will be charged whenever the insulin reservoir is refilled. The app will track feedings, insulin infusions and any discrete blood glucose measurements. Based on glucose measurements, the insulin dose will be adjusted and tracked over time.

Solution Components:

Mobile App

Android app

Will connect to pump over Bluetooth Low Energy (BLE)

View pump battery level

Dispense infusions

Track changes in blood glucose levels (inputted by user)

Track feedings and infusions

Delivery push notifications when dose/feeding is due

Will export the data for vet usage

Mobile App Backend

Database that will securely store user data

Google Firebase or a similar technology

Canine insulin pump hardware

Reliably and accurately dispense insulin

Rechargeable battery will last at least one week

Battery protection and charging circuitry

Low power ARM microcontroller manages device functionality

Connect to smartphone using BLE

Small enough to fit on a medium sized dog’s collar

Criterion for Success

All of the functionality for each solution component in the previous section works as described. Demonstrate that the correct amount of liquid can be dispensed, as commanded by the Android app.

Link to the idea:


The Donor Wall on the southwest side of first floor in ECEB is to celebrate and appreciate everyone who helped and donated for ECEB.

However, because of poor lighting and color contrast between the copper and the wall behind, donor names are not noticed as much as they should, especially after sunset.

Solution Overview:

Here is the image of the Donor Wall:

We are going to design and implement a dynamic and interactive illuminating system for the Donor Wall by installing LEDs on the background. LEDs can be placed behind the names to softly illuminate each name. LEDs can also fill in the transparent gaps in the “circuit board” to allow for interaction and dynamic animation.

And our project’s system would contain 2 basic modes:

Default mode: When there is nobody near the Donor Wall, the names are softly illuminated from the back of each name block.

Moving mode: When sensors detect any stimulation such as a person walking nearby, the LEDs are controlled to animate “current” or “pulses” flowing through the “circuit board” into name boards.

Depending on the progress of our project, we have some additional modes:

Pressing mode: When someone is physically pressing on a name block, detected by pressure sensors, the LEDs are controlled to

animate scattering of outgoing light, just as if a wave or light is emitted from that name block.

Solution Components:

Sensor Subsystem:

IR sensors (PIR modules or IR LEDs with phototransistor) or ultrasonic sensors to detect presence and proximity of people in front of the Donor Wall.

Pressure sensors to detect if someone is pressing on a block.

Lighting Subsystem:

A lot of LEDs is needed to be installed on the PCBs to be our lighting subsystem. These are hidden as much as possible so that people focus on the names instead of the LEDs.

Controlling Subsystem:

The main part of the system is the controlling unit. We plan to use a microprocessor to process the signal from those sensors and send signal to LEDs. And because the system has different modes, switching between them correctly is also important for the project.

Power Subsystem:

AC (Wall outlet; 120V, 60Hz) to DC (acceptable DC voltage and current applicable for our circuit design) power adapter or possible AC-DC converter circuit

Criterion for success:

Whole system should work correctly in each mode and switch between different modes correctly. The names should be highlighted in a comfortable and aesthetically pleasing way. Our project is acceptable for senior design because it contains both hardware and software parts dealing with signal processing, power, control, and circuit design with sensors.
