Connecting 2 PCBs which are placed one above the other

Hi All,

First of all I apologise for posting this question in the wrong group as I didn't find the appropriate field to choose from the drop down menu list. The kind of response that I get from ST community is very fast and appreciable so I didn't mind asking in this group.

My question : We are developing a medical device for measuring physical parameters. In the mechanical that we have chosen consists of 2 PCBs which are spaced at a height of 1.4 m inside the enclosure. I would like to know what type of board-to-board connector (FPC/FFC) should be used so that I can comfortably send 16 signals from one PCB to another.

Please help.
