SUMIT : Smart Urinalysis Module for an Innovative Toilet
Benefits of monitoring biomarkers in urine
- A biomarker contains measurable information about physiological state related to organ function, pathologic processes, or therapeutic interventions.
- A good biomarker, when monitored frequently, clearly reflects changes in physiological state.
- Urine is an ideal, but until recently overlooked, source of good biomarkers. Blood does not always reflect physiological changes, due to its homeostasis mechanism [Ref. 1].
- Urine, unlike blood, is abundantly excreted, and it can be accessed non-invasively.
- Urine biomarkers have been linked to [Ref. 2]:
– lifestyle: e.g., diet, supplement/drug intake, hydration, exercise, metabolism, circadian rhythms, and hormones;
– numerous diseases (e.g., diabetes, cancer, infections, and those related to kidney, liver, urinary tract, and cardiovascular functions).
(1) Quantitative, multiparameter, miniature, ultra-low-cost sensors. These sensors are developed in partnership with CSEM, the Swiss Center for Electronics and Microtechnology.
(2) Modular device design for addition onto any toilet, which avoids complex and costly incorporation into the ceramic toilet body. Automatic and hygienic sampling and analysis of urine from multiple users.
(3) Seamless data transmission from device to user’s mobile device via Bluetooth.
(4) Mobile app for user interface with device and result communication according to appropriate ranges. The app also provides recommendations regarding user’s: diet and supplement intake, hydration, exercise, and metabolism.
(5) Multiple target user segments, comprising:
– Young fitness and digital tech enthusiasts;
– Busy parents looking for time optimization in family’s health management;
– Elderly people who are looking for close prevention and follow-up.
Device, user interface, and app designed with expert consideration of user experience, in partnership with the EPFL+ECAL Lab.

In parallel to developing SUMIT for commercial applications on Earth, we are adapting the SUMIT technology for our (semi)closed-loop habitat demonstrator concept, using space technologies and requirements, in order to monitor urine composition for efficient urine valorization and close monitoring of crew health and wellness.
