Our Business

ADD develops medical devices and colour indicating technologies independently and in collaboration with partners.

Recently, we have focussed on the development of our pressure-indicating technologies, including: instantaneous pressure imaging sheet materials (a pressure-precise variant of carbonless copy paper), reversible pressure indicators and pressure & contact duration indicators. These technologies are patented or patent-pending and can be investigated further via the tabs above.

Below are some short video clips of our pressure indicating technologies.
