The Most Impactful New Technology at CES 2019

Some impacts are felt immediately, but some take years before we fully appreciate the significance of the scientific discovery or even how the invention will impact our world. Ten (10) years after Alexander Graham Bell invented the telephone, the world was still not sure if it would amount to anything. Twenty (20) years after John Logie Baird first demonstrated the television he was still being ridiculed for his “plywood box” that would have little future. Even the AC Motor invented by Nicola Tesla endured 15 years of debate and financial strain. One of the greatest critics of the technology was Thomas Edison.

So, how to introduce a new high impact technology in 2019 without a decade of debate? The demo should target a large impressive market, should be visually impactful, show what others cannot, solve problems others cannot, and demonstrate value that others cannot. Hopefully you will share my strong affinity for this new method of Low Voltage Drive-Sense after reviewing the initial list of “Industry Firsts”. We were fortunate to have had an audience at CES this year with some of the brightest technologist and industry leaders who are known to drive large markets. After the 5th person commented that this was the single most impactful technology they had seen at the show I felt compelled to write this post.

Our Team at SigmaSense® LLC has focused on Capacitive Imaging for touch screens, but our technology is a new method for Low Voltage Drive-Sense that will usher in a modern era of perceptive sensing, high precision control, high speed communications and much more. The technology simultaneously drives and senses without lag through noisy environments the smallest changes in voltage, current, capacitance, resistance, and/or frequency. Inventor Troy Gray built his first prototype nearly 3 years ago and the team has since demonstrated several industry firsts, any of which by itself would be enough to shake up the industry.

We picked the Large Interactive Display market as our first demonstration to the world. Capacitive sensing across a large screen is quite difficult and the technical challenges have stalled adoption of large touch screens. So, we picked this category specifically because we could solve some difficult challenges and to show relatively quickly the game changing impact of this LV (Low Voltage) Drive-Sense Technology.

What we have demonstrated is more than 8 significant “Industry Firsts”.
⦁ First “Capacitive Imaging” based touch controller (rather than scanning we image the entire front of the screen oversampling at 20 million samples/second)
⦁ First capacitive touch controller to deliver 300Hz report rate (all rows and all columns)
⦁ First low voltage touch controller to operate through thick glass (10X to 100X lower voltage than the rest of the industry)
⦁ First large screen touch controller with no perceived effects from attenuation of signal on long lines (great performance regardless of screen size)
⦁ First ICCI “In-Cell Capacitive Imaging” driving touch sensing simultaneously with display operations (think lower cost, higher resolution displays for mobile phones without limitation or added cost due to the touch sensor)
⦁ First touch controller to drive high resistance, non-uniform, optically pure sensors for large screens (high quality optics at low cost)
⦁ First touch controller with continuous and simultaneous drive and sensing of self-capacitance, mutual capacitance and pen (go from homework to gaming on the kitchen table in an instant)
⦁ First Sensor Fusion on a chip supporting high resolution measurement of: voltage, current, capacitance, resistance, and frequency (enables a new era of ultra-low voltage sensing and control).

We have enabled the world’s first ITO touch sensor on an 86-inch display delivering high performance touch sensing through 7mm thick cover glass, using gloves, and even through conductive liquid on the screen, while reporting all rows and columns at 300 frames per second.

This technology will have tremendous impact within the display industry but we are especially excited about the impact to a wide range of other markets, including Automotive, Aviation, Medical, IoT, Batteries, Power Management, Industrial, Ultrasound, and a number of other high-volume drive-sense applications. The real excitement of this technology is its applications beyond touch sensing. It is a break from the traditional threshold-based scanning systems that dominate the digital interface to a noisy analog world. What we demonstrated was touch sensing on a large screen, but the full range of what we do with the technology will have profound impact on people’s daily lives.

It has taken SigmaSense® 3 years to build a demo that properly shows the impact and potential of this breakthrough technology. As sometimes happens, we have just opened a door and found behind it a room full of even more high impact applications. SigmaSense® is just getting started and we can promise that the greatest benefits for people and the greatest impact to the world has yet to be felt.
