LumenAstra was formed in 2020 to commercialize a patent from the EE Dept at the Univ of Colorado for a non-invasive, wearable deep-tissue temperature sensor. This sensor technology has applications in cancer hyperthermia therapy, hypothermia (cooling) for aortic dissection repair, brain temperature monitoring for neo-natal HIE Hypoxia Ischemia, internal heat stress monitoring for military, hazardous environments or athletics and post-stoke or shock patients.
