Safety Starts With Knowing
Our mission
1 in 5 mothers are affected by Postpartum Hemorrhaging (PPH) worldwide..
What if we could give every mother the ability to silently monitor her own recovery—and alert caregivers before it's too late?
We are developing a comfortable, intuitive, non-invasive device tailored to postpartum women, especially in the critical hours and days after delivery.
Our Team
We are a group of biomedical engineering graduate students with the aim to help mothers globally.
As a part of the Innovate4Health Hackathon Challenge, we want to address gaps in gender and diverse health, specifically concerning postpartum mothers.
The lack of convenient at-home monitoring devices contributes greatly to maternal morbitidy. We hope to be a part of the solution.
The Challenge…
What is PPH?
Postpartum Hemorrhage (PPH) is one of the leading causes of maternal death worldwide. It occurs when a woman experiences excessive bleeding after childbirth—typically more than 500 mL after a vaginal delivery or 1000 mL after a cesarean section. While some cases are treatable in hospitals, others go unnoticed once the mother returns home, leading to delayed intervention and, tragically, preventable fatalities. In low-resource or even at-home care settings, early detection can mean the difference between life and death.
Delayed PPH..
Postpartum Hemorrhage (PPH) isn’t always immediate. In fact, delayed or secondary PPH can occur any time between 24 hours and 6 weeks after delivery, often striking unexpectedly after discharge from a hospital or hospice care (typically 24 hours postpartum).
Without proper monitoring, warning signs can go unnoticed until it’s too late.
What is our solution?
We’ve created a dual-sensor wearable that pairs a wristband and an abdominal patch with the aim to continuously monitor signs of internal blood loss for early detection before PPH happens.
Using cutting-edge technology, our wristband tracks deep-tissue blood volume changes. Meanwhile, our abdominal patch monitors uterine blood flow. Together, these sensors provide real-time data on hemodynamic shifts—the silent indicators of early-stage PPH.
The Design..
Our system is built for usability:
Compact and comfortable for mothers to wear at home or on-the-go
App alerts (buzzers) for immediate notifications, connected to your health provider’s system
Rechargeable battery that supports several days of continuous use
Affordable components, allowing scalability in high-need populations
Made with moms in mind..
We know that technology is only as powerful as it is accessible. That’s why our team prioritized an ergonomic design, intuitive software, and materials that are safe for sensitive skin. Whether it’s a new mother recovering in her own home or a rural clinic lacking round-the-clock monitoring, the Matriva wearable ensures that no sign of danger goes unseen.
Want to give us some feedback and ideas for design? Please take a look at our survey and give us your thoughts! We want to make sure this is ideal for mommas everywhere.
What stage are we in now?
We are in the stages of prototype production and are presenting our device and demo April 7th, 2025.
