Help TEWH Develop Low-Cost Medical Solutions

About Us


We are Texas Engineering World Health, an organization that creates innovative technology for low-middle income countries (LMICs) in a mission to make healthcare accessible and effective for those who need it the most. There are several factors for hospitals in the developing world not being able to provide effective care. Among these issues are cost-effective equipment and unreliable electricity. Texas Engineering World Health aims to tackle these social issue by building a new medical devices each year that are conscious of the infrastructure of the LMICs they will be used in.


Each year, our organization chooses a few projects that will help improve the lives and health of countless individuals in LMICs. This year, we have chosen 2 projects: 

Alternative-Powered Drug Refrigeration 

In LMIC hospitals, the refrigerator is one of the major devices that consumes the most power. Additionally, power can be unreliable in hospitals situated within rural communities. When power outages occur, hospitals can be left without power. This is especially bad for the refrigerator, which stores temperature sensitive drugs. We propose an innovative refrigeration unit that is able to minimize dependence on electricity by running on solar power in the daytime and radiative cooling during the night time. The point is not to have this refrigerator completely powered without electricity, but to make sure that running on electricity is the last resort. 

Mobile Patient Health Monitor 

In the developing world, the lack of patient health monitors leads to the occurrence of many preventable deaths. These monitors are in very low supply and it is our goal to develop a low-cost device that can monitor the patients vitals while not restricting their mobility. Our objective is to design a device that utilizes a simple user interface to communicate important information about the patient's health which can reduce the doctor's workload. 


How You Can Help


Your contributions fuel our organization! For all these projects, we will need to prototype physically. Your donations will support the purchase of prototype parts. Additionally, the Engineering World Health competition we enter our devices in annually requires a large entry fee for prototype submission in return for professional feedback on how our devices can be improved. Lastly, your contributions keep student membership dues low. We are grateful to each and everyone of you as your donations allow us to make a global impact every year.

Choose a giving level


Drug Refrigeration at 2-8 °C

A medication refrigerator should provide a stable temperature between 2-8 degrees Celsius, or 36 t 46 degrees Fahrenheit.


Average BPM of Heart

The average heart rate of a patient is 60 BPM.


Diastolic Blood Pressure

A patient's normal diastolic blood pressure should be below 80 mmHg.


Systolic Blood Pressure

A patient's normal Systolic blood pressure should be below 120 mmHg.


Generator Costs

In sub-Saharan Africa, the amount spent on generator fuel alone is equal to 15% of healthcare spending and 20% of education spending.


Ancient Radiative Cooling

In 400 BCE, Persians were building structures called Yakchals, which create ice through radiative cooling.
