Hi,

I am working on a project involving a handheld device that communicates over an RF link to a PIC18F6520 in the main control unit. I have tried various ways of making reliable contact arrangements to charge the battery in the handheld unit, however, as it is a hostile environment, most contact type methods have some shortcomings.

Does anyone have any experience with ideas, products or modules used for contactless charging in situations such as this? It would be nice to be able to incorporate this into existing projects too. All ideas welcome.

Andy
