PainChek (formerly ePAT Technologies) is software developer associated with Curtin University. It has developed an app that uses facial recognition and pain indicators to provide an objective pain assessment of patients who are unable to communicate with their carers.
In September 2017, ePAT listed on the ASX via a reverse takeover of Minquest. At the time of listing, the company's corporate offices were located in Sydney but its research operations continued to be based in Perth.
In January 2018, the company changed its name to PainChek to match the global branding of its core product.
