Hemorai is a healthcare technology company on a mission to detect Postpartum Hemorrhage (PPH) and enhance maternal healthcare outcomes.  Our cutting-edge wearable medical device is designed to monitor vital physiological parameters, including blood flow, blood pressure, and other critical indicators in real-time

Hemorai is addressing the critical issue of Acute PPH

The Problem

The problem Hemorai is solving is the timely detection of Acute PPH through innovative wearable technology and real-time monitoring of vital physiological parameters, ultimately saving the lives of mothers and ensuring their well-being during and after childbirth.

Rapid measurements of speckle contrast & diffuse reflectance

The Solution

Speckle Plethysmography (SPG) marks a significant advancement over Photoplethysmography (PPG), excelling in hemodynamic readings, particularly for patients of color, with four times the accuracy and reduced susceptibility to motion artifacts. 

Why is Hemorai the best option?


By creating a wearable monitoring device, we ensure that women from various socio-economic backgrounds can have access to advanced healthcare technologies. This device can be used in diverse settings, from high-resource hospital environments to low-resource settings, such as remote areas and home births.

Education and Empowerment

The user-friendly design of our device allows for mothers and their caregivers to understand and monitor postpartum health indicators. This empowers them with knowledge and the capability to seek timely medical help, which is critical in preventing adverse outcomes.

Equity in Healthcare

Our device's effectiveness across different skin tones addresses the disparity often found in medical devices that are not calibrated for darker skin. This commitment to inclusivity ensures that our technology provides accurate monitoring for all women, regardless of racial or ethnic background.

Economic Barriers

By providing a tool that enhances the early detection of PPH, we potentially reduce the need for expensive medical interventions that can be financially devastating for families. Early intervention can lead to better health outcomes and lower healthcare costs.

Data-Driven Solutions

The data collected by our devices can inform healthcare providers and policymakers about the prevalence and risk factors for PPH in specific populations, helping to shape more effective, targeted health programs and policies.


By providing a reusable, durable device with a long battery life, we ensure sustainable healthcare support that aligns with the environmental and economic aspects of social health determinants.

Tim Phillips, Ph.D. is a mechanical engineer with a passion for design and manufacturing. At Hemorai and as a consultant, he has driven the design process for numerous biomedical devices, including optical imaging systems, tissue harvesting probes, and medical storage monitoring devices. Tim has experience taking these ideas from rough sketches through ideation and prototyping and into early-stage production.

As a researcher, Tim has focused on improving control for manufacturing systems and developing new functional materials for Additive Manufacturing.  Dr. Phillips has worked on developing flaw detection methods in Additive Manufacturing systems and designed novel control architectures to improve manufacturing outcomes. He has also created and evaluated unique materials for Additive Manufacturing, such as lithium-ion battery materials, high-temperature ceramics, and high-strength implantable polymers.

Nitesh Katta, Ph.D. worked in the field of applied electrical engineering for more than 12 years. Nitesh has worked in the field of biomedical optics and fundamental laser-surgery research for more than 6 years. As part of his doctoral dissertation, he developed bench-top and catheter systems for image-guided surgery for brain cancer tumor resection in in vivo xenograft murine models. Nitesh is one of the early developers of precision in vivolaser surgery for brain cancer utilizing optical coherence tomography (OCT). 

Austin McElroy, M.Sc. has been a research scientist for over 15 years in almost all aspects of Electrical Engineering: circuit design, embedded systems, high speed parallel computing, and machine learning. Mr. McElroy’s master’s work mainly focused on biomedical optics and imaging, Austin has expanded his expertise to other bio-signals such as EEG and EKG data acquisition and wireless transmission.  As a lead software architect in two labs, Mr. McElroy often managed and coordinated graduate students’ efforts ensuring projects were completed on time within the scope of the budget. Many of these projects were funded by the NIH and NSF, so he has an appreciation for cost sensitivity and addressing problems as they arise within the scope of the proposed budget.


Wearable for Continuous Monitoring of Hemorrhage using Speckle Photoplethysmography (SPG)

Hemorai is improving on a technology developed by UCI with the name of coherent spatial imaging (CSI) system that combines the optical property measurements of srDRS with SPG- based blood flow measurements. This CSI technique allows high-speed measurements of speckle contrast and diffuse reflectance,  which provide critical information to assess absolute measurements of pulsatile blood flow, blood volume, stO2, and tMRO2. Using miniaturized optoelectronic components allows us to map radially-varying diffuse reflectance of coherent light from tissues, which in turn enables absolute measurement of absorption and scattering contrast. As the supply and utilization of oxygen can become decoupled in abnormal physiological states, CSI has the potential to measure the hemodynamic dysfunction that is expected to occur during early stages of hemorrhage.
