Please note: This is a Sole Source Notification. Specifications include, but are not limited to: The Center on Mindfulness and Integrative Health Intervention Development at the College of Social Work uses the mEMA sense application from Illumivu, which was developed for the Center based on custom specifications. The custom script uses heart rate variability data from a Garmin Vivosmart device to trigger mindfulness meditation audio recordings to be played from the mEMA sense smartphone app when a participant is experiencing stress. No other suppliers have developed a similar system and the cost to transition to a different product at this point would require custom development of a whole new app, making it is cost prohibitive.
