The following are taken from the paper:
Our company has been developing automotive capacitive sensor modules to sense human body proximity or contact. Our recent study aiming at increased accuracy achieved 2 fF or better capacitance sensing accuracy, making it possible to detect a human body 300 mm away, a distance longer than that possible with existing capacitive sensors. In addition, the sensor electrode structure used in a vehicle cabin was optimized to increase noise resistance and directivity. Furthermore, we made a prototype sensor module and assessed its sensitivity in the vehicle cabin, with the ﬁnding that the prototype module is able to sense a hand at a distance of 300 mm or more from the sensor electrode.
