Work: 2016–2022 · Company project; evaluated in published ICU studies
Hospitals need to know whether staff clean their hands when required and how long they spend doing it. A monitoring system also needs to fit into their daily work and give reminders when needed.
Microsensor Labs developed Sanibit for this purpose. A sensor wristband and wireless controllers detect when hand hygiene is needed and when it happens. The system gives private reminders and collects data to help hospitals measure compliance.
My work on sensors and firmware
I led sensor algorithm and embedded software development, from early prototypes to systems used in NIH-funded clinical studies and a beta product.
- Developed motion-tracking and sensor-fusion algorithms to detect hand hygiene activity and measure hand-rubbing time.
- Wrote wristband firmware for sensing, Bluetooth Low Energy communication, reminders and feedback.
- Led software development for controllers, gateways and wristband chargers.
- Integrated the algorithms and firmware into systems used in Phase I and Phase II clinical research.
Sanibit was evaluated in published ICU studies. I am a co-first author of Implementing an electronic hand hygiene system improved compliance in the intensive care unit, published in the American Journal of Infection Control in 2021.
