Tendo Technologies

Tendo is a technology company that provides innovative, economical solutions to accurate flow rate and pressure measurements that are extremely challenging to obtain. We seek to leverage the advancement and expertise in high fidelity flow measurements developed in Princeton’s Mechanical and Aerospace Engineering Department to drastically improve the fidelity of flow sensing at a significantly reduced cost. We are commercializing a new invention developed at Princeton called the Elastic Filament Velocimetry (EFV, patent pending), based on a novel yet simple microribbon structure, which resulted in a highly sensitive sensor that can detect flow rates as low as 0.5mL/hour – smaller than any technology available. The batch processes used for manufacturing the sensors can easily reduce the sensor cost to less than 50 cents at scale. The EFV technology is ideal for administering medical injections because of its sensitivity and low cost. As a versatile platform, the EFV can be operated in any fluid (both liquid and gaseous) and has attracted interests from other industries such as HVAC systems.

    Yuyang Fan GS6

    Yuyang is a sixth-year PhD student in the Department of Mechanical and Aerospace Engineering at Princeton and a co-founder of Tendo Technologies. He holds a BS in Mechanical Engineering from Caltech and a BA in Physics from Grinnell College. His research is on developing high resolution sensors for turbulence measurements using semiconductor fabrication techniques. Prior to joining Princeton, he helped to build a solar-powered house to enter the DOE Solar Decathlon competition and became a certified plumber because of that.

    Matthew Fu GS5

    Hailing from the great state of Virginia, Matt Fu is a fifth-year PhD student in the Mechanical and Aerospace Engineering Department and holds a BS in Mechanical Engineering from Caltech. He spends his days conducting research in turbulence and fluid mechanics and spends his nights thinking about conducting his research in turbulence and fluid mechanics. Matt’s work centers around physical modeling, with a current focus on turbulent drag reduction using liquid-infused surfaces and development of novel high fidelity flow sensors. One day he would like to meet Joe Biden.
