| 摘要 |
A sensor interface (10) is disclosed including a flexible substrate (12) within which are embedded sensors (22, 24, 26) for measuring physical parameters such as temperature, displacement, velocity, acceleration, stress, strain, pressure and force present between objects (18, 20) such as a railcar bearing (44) and a truck side frame (48) The substrate (12) is positioned between the objects ( 18, 20) of interest Electronic components such as a data processing unit (28), a data storage device (32), a communication device (34), and a power source (38) may also be embedded within the substrate The electronic devices (28, 32, 34, 38) communicate with one another and the sensors (22, 24, 26) to process signals generated by the sensors (22, 24, 26) indicative of the parameters being measured. |
