TouchNetix has added to its aXiom family of HMI chips with the release of a pure Force-Sensing chip – the AX54A-Force. This is a perfect small-sized chip to complement smart touch surfaces, touch button clusters and other solutions where touch functionality is integrated.
TouchNetix’ unique and patented Force-Sensing technology is gaining significant momentum in automotive and industrial markets, providing modern and safety-enhancing human-machine interfaces (HMI) for multiple car OEM platforms. The integrated Force-Sensing technology in aXiom provides accurate and highly sensitive force-sensing data to the user interface.
TouchNetix’ integrated Force-Sensing technology enables accurate and reliable measurements of force on the touchscreen or surface from 0.1 Newton (10 g) to 20 Newton (2000 g). The aXiom technology also offers unique multi-force position sensing down to a spatial separation of 1.5 cm. The superior sensitivity and signal-to-noise ratio (SNR) of the aXiom chips enables detection of the smallest force signals, with extremely fine precision. The technology also allows a wide range of forces to be detected to cater for all requirements.
TouchNetix also offers Dial-on-Display features that are integrated within the aXiom touch solutions. Additionally, aXiom enables touchless user interfaces by accurately sensing the presence or position of a user’s finger above the touchscreen or touch surface. User interfaces developed using aXiom technology can utilize Force-Sensing to verify the user intent by requiring an additional press and therefore avoiding inaccurate touch instructions from an errant finger in a moving vehicle. By combining the multi-force technology with parallel multi-touch measurements, the aXiom HMI chips offer safety-enhancing systemic redundancy from two separate sensor measurement systems.
The TouchNetix patented Force-Sensing technology is mechanically easy to integrate as it uses off the shelf and low-cost components, and materials that are automotive qualified. The technology acts to absorb any mechanical stack tolerances offering enhanced mechanical and manufacturing reliability. All aXiom chips are qualified according to AEC-Q100.
Gaute Myklebust, Chief Technology Officer of TouchNetix commented, “Many customers realize the safety-enhancing advantage of having redundant Touch and Force detection in their systems. Moreover, our easy-to-use and low-cost Force-Sensing solution offers the additional confirmation action you require in modern automotive and industrial HMI solutions, to confirm the user intent for specific functions.”
