Systems and methods for providing screw bosses on a substrate. The substrate can be dimpled. The dimples can then be threaded to accept screw bosses. The dimples can be threaded using a threading die or can have threads cut by self-tapping screw bosses. An adhesive can be applied to the substrate, the bottom of the screw boss, or both. The screw bosses can include standoffs to determine the distance between the bottom of the screw boss and the substrate. The screw bosses can be threaded onto the dimples and can provide threads for attaching items to the substrate. A filler material can be applied to the reverse side of the substrate to fill-in the dimples and present a smooth surface. A decorative or protective layer can be applied over the filler material.

One or more items of apparel have a plurality of sensors (and) disposed therein (either permanently or temporarily). These sensors sense physical states of the individual wearing the items of apparel and/or of the local environment. In one embodiment, multiple sensors sense, in alternative ways, a parameter that corresponds to a physical state of interest. Information from these alternative sensing approaches is co-processed to yield a resultant parameter value that can be used in various ways. In one embodiment, the parameter value is locally or remotely displayed. In one embodiment, the parameter value is used in comparison against risk thresholds to ascertain a degree of risk to the individual.

The organic MEMS according to the present invention comprises a polymeric substrate comprising a substrate surface including a first region and a second region. A polymer coating is applied to the first region to provide a coating surface that is spaced apart from the substrate surface. A terminal is disposed on the second region. A metallic trace is affixed to the coating surface such that the metallic trace forms a flexible extension over the second region. The extension has a rest position where the extension is spaced apart from the terminal, and a flexed position where the extension is disposed towards the terminal. An actuator is used to provide an electric field to deflect the extension from the rest position to the flexed position. By changing the spacing between the extension and the terminal, it is possible to change the electrical condition provided by the MEMS.
