Abstract
A piezoresistive pressure-measuring plug for a combustion engine. The pressure-measuring plug includes a plug body having a threaded plug body part with an external thread for screwing the plug body into a cylinder of the combustion engine, and a sealing plug body part forming a tip of the plug for providing a seal between the plug body and the combustion engine. The plug body further includes a sensing body part positioned between the threaded plug body part and the sealing plug body part. The sensing body part includes a cylindrical body part, a moving part, and a sensing structure that form a single integral piece. The sensing structure forms a connection between the cylindrical body part and the moving part, and allows the moving part to move relatively to the cylindrical body part along a cylinder axis of the cylindrical body part.
