UltraSense Systems has released the CapForce Edge, an advanced capacitive sensing controller integrated with high-resolution piezo-based force sensing. Designed for modern smart surfaces across automotive, consumer, industrial, and robotics markets, CapForce Edge enables precision, noise immunity and integration.
CapForce Edge offers best-in-class capacitive sensing performance featuring frequency hopping and active shield technology to combat electromagnetic interference (EMI), critical for reliable operation in electrically noisy environments. Its performance is on par with the best capacitive controllers on the market, UltraSense Systems says. Uses cases include the steering wheels, center consoles, door handles and exterior touch zones of automotives.
The controller features a fully integrated eight-channel piezoelectric force sensing, enabling simultaneous detection of both touch and press with a single chip. Additionally, UltraSense’s proprietary piezoelectric force sensor technology is said to offer a highly repeatable and stable performance, unaffected by manufacturing tolerances, temperature variation and environmental stressors, enabling robust integration across diverse applications.
“With CapForce Edge, we’re delivering a world-class capacitive controller that rivals any standalone solution, but we go further by integrating force sensing into the same silicon,” said Mo Maghsoudnia, founder and CEO of UltraSense Systems. “It’s a breakthrough for designers building smart surfaces that demand both precision and compactness.”
CapForce Edge combines 24-channel capacitive touch sensing with advanced EMI mitigation, frequency hopping for dynamic noise avoidance and active shielding to ensure signal stability in harsh environments. It also features 8-channel piezo-force sensing with high linearity and fast response, along with a 16-bit ADC integrated with an embedded sensor-fusion MCU for intelligent input processing.
It also features multi-protocol support, including I²C (Master/Slave), SPI and LIN-compatible UART, as well as 10 programmable GPIOs with PWM output. The combination of features enables the creation of robust, sealed, buttonless interfaces through materials like metal, glass and other surfaces.
