According to various implementations, a sensor mat includes a mat substrate, a sensor electrode, and a shield electrode. At least a portion of the sensor and shield electrodes are spaced apart from and parallel to each other on a first surface of the mat substrate. The shield electrode is electrically coupled to a voltage source to create a capacitance between the shield electrode and the sensor electrode, and the sensor electrode is used to detect a change in the capacitance. The shield electrode may also be alternately used for heating the surface of the vehicle part adjacent the mat. For example, the sensor may be disposed adjacent a portion of a steering wheel or a seat assembly and is used for sensing presence of an occupant's hands or body adjacent the steering wheel or seat assembly.
根据各种实施方式,公开了一种传感器垫包括垫基板、传感器电极以及屏蔽电极。在垫基板的第一表面上,传感器电极的至少一部和屏蔽电极的至少一部分彼此间隔开并且彼此平行。屏蔽电极电连接到电压源以在屏蔽电极与传感器电极之间产生电容,并且传感器电极用于检测电容的变化。屏蔽电极也可以交替地用于加热垫附近的车辆部件的表面。例如,传感器可以邻近方向盘或座椅组件的一部分设置,并且用于感测邻近方向盘或座椅组件的乘员的手或身体的存在。
