Inventor Spotlight: Patrick Troy Gray and the SigmaSense Sigma-Delta AFE Revolution
Innovation often begins with a single mind willing to rethink the impossible. For Patrick Troy Gray, co-founder of SigmaSense, that meant reimagining how machines sense and respond to the world around them.
With decades of experience in capacitive touch science, Troy built a career at the intersection of invention and application. He founded TouchKO, a company recognized for pioneering touchscreen R&D, and later contributed to global sensing patents at Wacom. His inventive spirit consistently pushed the boundaries of human-machine interaction.
At SigmaSense, Troy’s vision led to the creation of a novel sigma-delta architecture that transformed impedance sensing. By moving sensing into the digital domain, his approach enabled continuous, ultra-low voltage operation with unprecedented signal-to-noise ratios. This breakthrough embodied in SigmaSense’s SigmaDrive® technology – opened the door to applications across consumer electronics, automotive systems, medical diagnostics, and energy storage.
Alongside co-founder Shawn Gray, who brought operational leadership and commercialization expertise, Shawn helped secure the initial angel funding and drive the IP portfolio to more than 300 patents. Together, they were the foundation that enabled SigmaSense to reshape the future of touch, sensing, and digital interaction.
Troy Gray’s legacy is not just in the patents he authored or the companies he built, but in the way he redefined what sensing could mean for the future. His work exemplifies how a single inventor’s vision can ripple across industries, reshaping the way we interact with technology every day.
SigmaSense stands as proof that invention is not about incremental change – it’s about daring to redefine the rules and think outside the box.
