So you have developed a technology that you believe can be a viable electro-mechanical device but you only have a lab or bench top concept right now. You will need to present your idea and get investors interested so you can start some fund raising rounds to go forward. Nothing speaks to people like being able to hold something in their hand.
So you have developed new technology or processes, so what are your next steps?
Of course funding is fundamentally important, but for physical device technology development, your business plan should in parallel consider developing a manufacturable design and prototype while also protecting your intellectual property.
