The present invention is directed to a sensing modality for measurement of vital signs, particularly in neonates, using inkjet-printed sensors in order to create a low cost and computationally less-intensive monitor. The invention incorporates the use of sensors specifically design to measure abdominal flex as a measure of their respiration rate. Neonates in particular exhibit abdominal flex during respiration. The flex sensor can be coupled with other off-the-shelf sensors or sensors made using same principles, connected together to a phone through the AUX port of a cell phone or other device for data collection and processing. The sensor can also be configured to communicate wirelessly with a computing device, such as a smartphone.
