SigmaSense offers a software‑defined, direct‑to‑digital sensing platform that measures current in the frequency domain, eliminating traditional analog front‑ends to provide ultra‑low‑noise, high‑resolution data. Its two product families—SigmaEIS for real‑time battery health monitoring via electrochemical impedance spectroscopy, and SigmaDrive® SDC300 for precise touch and touch‑less gesture detection on large or high‑capacitance displays—enable OEMs and system integrators to create faster, more accurate, and software‑configurable interactive and energy‑storage solutions.

Problem
Current sensing solutions for touch interfaces, battery monitoring, and other IoT applications rely on analog signal conditioning, limited bandwidth, and noisy measurements, which restrict speed, accuracy, and design flexibility. These constraints make it difficult to create large‑area, high‑resolution touch displays, real‑time battery health analytics, and reliable sensing in harsh or low‑signal environments.
Solution
SigmaSense provides a software‑defined, direct‑to‑digital sensing platform that measures current in the frequency domain using a highly modified sigma‑delta architecture. By converting impedance changes to digital data at the sensor level, the technology eliminates traditional analog front‑ends, reduces noise, and delivers ultra‑fast, high‑resolution measurements. The same core engine powers two product families: SigmaEIS for batteries, which continuously monitors complex electrochemical impedance to give real‑time health, safety, and performance insights; and SigmaDrive® SDC300 for interactive displays, which enables precise touch and touch‑less gesture detection on large, thin, or high‑capacitance surfaces. The digital‑first approach also supports closed‑loop drive and self‑biasing, allowing designers to iterate quickly with software control and integrate the sensors into AI‑enabled systems.
Target Audience
Primary customers are OEMs and system integrators developing large‑area interactive displays, automotive cockpits, gaming kiosks, and rugged industrial interfaces, as well as battery manufacturers and energy‑storage providers needing real‑time health analytics.
