ProxLogs - miniaturised proximity loggers

We have developed miniaturised proximity loggers (smallest model is ~1g) that can be used to gather high resolution social and spatial information on animal behaviour in the field. Our initial prototypes have worked in a number of different test settings now, and we are confident that the loggers do collect the data. Our next challenge is twofold - what are good sources of funding to help develop the improvements we now want to make - can anyone suggest any good ones? And what is the best way to make the loggers accessible to people? I have been considering the groupgets approach that has been so well demonstrated by the Audiomoth project, but I was wondering what peoples thoughts were? I am also cautious about the time investment that would be necessary for the different approaches (this is a passion project rather than strictly speaking part of my current position).
