JHU Engineering

Design Day

Johns Hopkins Engineering Design Day is the Whiting School’s premier event that showcases the innovative works of Hopkins engineering students. Come see how students implement their classroom knowledge, creativity, and problem-solving skills to develop inventions and processes that solve real-world problems and create a better future.​​

Congratulations to all on a fantastic 2025 event!

Information on JHU Engineering Design Day 2026 coming soon.

Zephyrix: A multiplexed viral breathalyzer for rapid point-of-care diagnostics

We have designed a breathalyzer device for rapid capture and detection of > 6 unique viruses. Users unwrap a single-use cartridge and insert into the electronic device. Users then blow into the device into a multilayer hydrogel, which hydrates to form a fluid phase and enables viral suspension simultaneously. The captured condensate is pulled down to a molecularly imprinted polymer (MIP) surface, which selectively and efficiently binds to viruses of interest. This binding creates electrical impedance which encodes captured viral concentration, which is reported to the user via an OLED readout of respective presence of each of the six viruses. The device has built-in control to ensure sufficient breath volume and is completely non-invasive and reagent-free. This system has utility in a medical triage setting such as urgent care/ER facilities as well as nursing homes and chemotherapy centers, where rapid, cheap testing is necessary.

Assembly of Anisotropic Colloidal Materials and Shapes in Electric Fields

This project explores how various collodiol materials can be manipulated in AC electric fields for applications in aerospace, defense, and soft robotics. Materials investigated include SU-8, Lithium Iron Phosphate (LFP) Lithium Aluminum Titanium Phosphate (LATP), and Sodium Super Ionic Conductor (NASICON). These materials were examined for their ability to respond to electric fields, with particular focus on the interactions between particles and the field, such as the dipole-field potential.
