SigmaSense has announced a license and co-development with NXP® Semiconductors to lead in the transition from traditional touch interfaces to multi-dimensional sensing capable of revolutionizing user experiences. SigmaSense has licensed technology to NXP, and the companies will collaborate on high-performance sensing products for specific applications with demands for faster, more robust, fully immersive software-defined experiences.
SigmaSense innovations make it possible to extract vastly more data from the physical world for a wide range of products and systems. Multi-dimensional sensing works through many different surfaces, shapes, and materials, enabling previously impossible designs. With the invention of measuring current direct-to-digital, SigmaSense delivers low-voltage, frequency domain sensing, an industry first. Fast, continuous, high-fidelity data capture with intelligent digital signal processing moves analog challenges to the digital domain, where design flexibility can deliver orders of magnitude improvement. SigmaSense is changing system designs from foldable displays to EV batteries.
The direct-to-digital sensing system is a closed loop, self-biased, current based ADC that interfaces directly to the sensor network and receives analog input as an electrical current. The analog input current can be of any magnitude, even as low as pico-amperes, and digitized directly into a high-resolution digital format. This eliminates many of the challenges of designing with traditional voltage-based ADC converters while providing continuous high-fidelity digital data. Once the signal is converted into its digital form, the signal can be post-processed using modern DSP techniques for noise reduction, filtering and active noise cancellation.
This direct-to-digital sensing technology delivers high performance, low power consumption, high channel count, and small die area for lower cost.
Sensing current direct-to-digital makes possible operation with ultra-low voltage enabling continuous real-time operation. Continuous digital data in turn enables dynamic noise mitigation resulting in over 100x improvement in SNR, diminishing the long-standing design tradeoffs between speed, noise and accuracy.
Operating in the frequency domain delivers high sensitivity creating a new industry benchmark. The result of high speed (300-600 Hz) at ultra-low voltages (less than 1-V) capturing 1000x more high resolution data that is then managed by programmable software to create superior experiences. The ability to operate in noisy environments with high sensitivity performing dynamic noise mitigation in real-time opens the door to new features and interactions.
Sigmasense leads the industry operating with high resistance conductors that enable use of lower cost and flexible materials. These include flexible polymer conductors, which offer better optics, lower cost, more design flexibility, architectural efficiency, and improved noise immunity. This makes possible a range of innovations including large fast displays, elastromeric foldable display designs, and new biosensing wearables.
“The next generation of smart devices and applications are demanding data for enhanced functionality that requires an entirely new software-programmable approach to sensing,” said Lars Reger, CTO, NXP Semiconductors. “SigmaSense created a breakthrough in sensing technology with an innovative approach that makes exciting new product designs possible.”
“NXP’s prowess in highly dependable products and deep expertise in high-volume semiconductor design combined with SigmaSense technology will accelerate game-changing sensing products,” said Rick Seger, CEO, SigmaSense. “Our co-development with NXP marks the transition to a universe of new data- centric design options driven by software-defined sensing.”
