A cylinder liner for an internal combustion engine is formed of cylindrical liner body having an interior cavity with a cylindrical inner surface, a sensor embedded in the cylindrical liner body and being configured for sensing a physical condition on the cylindrical inner surface, and a transmitter connected to the cylindrical liner body at a position remote from the sensor. A connecting wire connects the transmitter to the sensor, and is embedded in in the cylindrical liner body. The sensor is located in an upper portion of the cylindrical liner body and the transmitter is located directly below the sensor, such that the wire runs vertically. The transmitter can send information obtained by the sensor to a remote processor for calculating various operating states of the liner.

A novel and useful pressure sensor array incorporating sensor elements constructed from electrically conductive film as a substrate. Examples of commercially available electrically conductive (i.e. piezoresistive) film include Velostat and Linqstat. A wearable device is described incorporating an array of pressure sensors with flexible properties and a biocompatible material interface between the sensor elements and a user's skin. The pressure sensor array uses the electrically conductive film as a substrate and places a pair of conductors in a suitable configuration to form individual sensor elements. The sensor elements detect the change in resistance of the electrically conductive film when pressure is applied thereto. The sensor elements may be implemented in an interdigitated or opposing configuration. The sensor array also comprises a mechanical interface on top of the sensor elements for transferring or focusing the applied pressure to the electrically conductive film.
