This experiment is not currently targeted for archival. However, limited information may be available.


The International Space Station (ISS) is equipped for health and life sciences research with various research/medical instruments. However, currently available instrumentation is not suited for the continuous monitoring of crewmember physiological parameters for prolonged periods. Moreover, several devices are often required if more than one parameter needs to be monitored. This situation is time-consuming, often limits crewmember mobility, and involves complicated data management. The Canadian Space Agency (CSA) is collaborating with industry to build a bio-monitoring system (Bio-Monitor) capable of measuring and recording several physiological parameters continuously for up to 48 hours. The proposed Bio-Monitor system should will address the lack of instrumentation availability on ISS in the form of a non-invasive, non-intrusive wearable multi-sensor system.

The Bio-Monitor system is intended to allow on-orbit monitoring of several physiological parameters simultaneously. Measurements from the system are comparable to those provided by currently available technologies used for clinical purposes on the ground. This device will produce data in sufficient quality to meet research criteria and is based on wearable sensors that only minimally interfere with crewmember daily activities. Additionally, this system can also prove to be well adapted to monitor physiological parameters in elderly or bed-ridden people on Earth.

The aim of this research is to validate the operability and functions of the Bio-Monitor system in weightlessness.

This validation covers:

  1. Operation and data recording functions of the system.
  2. Data handling and transfer between system components and to the Principal Investigator (PI).
  3. Sensors signal quality (level of noise, movement artifacts).
  4. Sensors signal accuracy (“physiological” accuracy).

Note: The data collected during the commissioning will not be used to provide any diagnostic data about the subject’s health status.
