Brewer Science's vision is to design, build, and deploy connected gas and water sensors that monitor environmental contaminants quantitatively on a large scale. For the last 10 years, Brewer Science has developed the technology to print cost-effective sensors that can measure contaminants in water, such as heavy metals (lead, cadmium), copper, nitrate, pH, and ORP, as well as sensors that assess air quality by measuring gases like carbon monoxide, carbon dioxide, hydrogen, VOCs, and oxygen. Brewer Science fabricates a variety of printable sensor materials and deposits them onto a substrate utilizing processes such as physical vapor deposition (PVD) sputtering, screen printing, stencil printing, ink-jet printing, and high-speed jet dispensing. Producing low-cost sensors with low-power electronics and wireless communication will enable the deployment of sensors over vast areas for real-time monitoring of environmental conditions.
