Primarily organized around Materials for Energy & Water, Sensors, and Semiconductors and with close ties to Arizona State University oftening in ful partnering mode, Cactus Materials has worked on a BioSkinPatch- a wearable remote ambulatory bio-monitoring sensor platform: a state-of-the-art physiological monitoring device using novel patent pending materials and ?trans-disciplinary studies. In the semi-conductor space, Cactus has worked on Wafer Nano-Bonding and on advanced ceramic packaging for WBG Semiconductors in High Power Electronics (Smart Grid, EV, Space in Venus). In the energy sector involving Ceramic R&D, the firm has worked on Solid State Ceramic Batteries and 2D Materials/Ceramics R&D - Graphene and Ceramics for Super-capacitors, Water Filter, and Desalination. In the Solar Energy Systems space projects have included MultiJunction Tandem Solar Cells for Space Applications (Q2' 2019) and III-V Thin film solar cells in roll to roll (Q2-2019) - TRL 3
