Background
Premature infants neonates born prior to 37 weeks of gestation
Most organ systems have not fully developed Apnea/problems breathing due to immature lungs or
pneumonia Lower muscle and activity compared to full-term infants Problems feeding due to difficulty sucking or
coordinating swallowing and breathing Less body fat Thin, smooth, shiny skin, which is often transparent (can
see veins under skin)
3
The Problem•Infants will have contact electrodes across skin, •Often causes
•Abrasions•Tears•Future scarring
4
Our Proposal
We propose the development of a smart vest for neonates with non-adhesive electrodes to collect vital biosignals, eliminating the need for potentially skin damaging adhesive.
5
Design Considerations
Over all construction Full jacket design small jacket Cloth neoprene Back vs. Front ECG acquisition
Lead/Pad Design Gold Non contact Self triangle design- non adhesive conductive
gel Conductive gel/pad replaceable vs. triangle unit
6
Sensors Commonly Used
Pulse Oximetry (SpO2) Able to be placed around
babies wrist ankle toe or hand
Chosen wrist/hand for ease of wiring
Respiratory Rate Band Babies are stomach
breathers therefore band goes around stomach
Cannot be to tight to prevent or slow breathing
Temperature sensor Not needed for most
babies Slot will be made on the
vest for sensor to go into
7
Current Design
Testing and Validation
Due to the nature of our project, all testing must occur on adults. The vest will be designed on the macro-scale and then scaled down to fit neonates between 500 g and 4.5 kg.

Social Impact Considerations
Parents must find the device appealing to the eye With less wires the babies will look more
“human” Hospitals with a agenda in personal comfort will
look a lot better to society Compilation of wire
Many wires that will be coming off/one bulky wire Wireless would greatly increase overall aesthetics
and mobility
10
Health and Safety Considerations
Vest cannot cause any stress on breathing
Cannot cause any allergic reactionsNo abrasions caused Vest needs to be small
Nurses and physician need to see as much of the baby as possible
Stomach much be visible to diagnose gastro issues
11
Other Considerations
Economic similar materials to that which is being used
currently addition of silicone to normally used product
Sustainability silicone is a durable substance neoprene durable substance-machine washable
Manufacturability silicone is easily mass produced molded very well
