Force sensor combines high resolution with high impact resistance
Designed for use in stylus pens and other input devices, the sensor exhibits high linearity (<2%FS), high resolution (detects micro force with less than 0.01 N), while at the same time realizing an improvement in impact resistance of up to 55 N. The sensor offers an operating life of 1,000,000 cycles and is resistant to external magnetic and electric fields.
The improved impact resistance of the sensor is achieved with the extension of the actuator diameter of the sensing zone from the existing 0.20 mm to the new 0.40 mm, while at the same time keeping the rounded peripheral edge to disperse impacts. Therefore, the breakage risk of the sensor in stylus pens is reduced in case the pen is unintentionally dropped, while still guaranteeing smooth pen pressure expression without spoiling the easy integration into end products. The sensor is also suitable for industrial machines handling precision equipment and a range of diverse applications, especially on the grip parts of robot arms for precision grip force adjustments.
