I was member of a team of two students and a professor, launching a startup project named Plug ‘n’ Scope in summer 2014 (see also www.plugnscope.com). We developed a smartphone-connectable digital stethoscope. Hardware development comprised the analog-digital conversion of the sounds in a classical stethoscope. The resulting digital signal was then transferred to a smartphone where our software analyzed the signal on typical pathological patterns. We developed a business plan, applied for funding from the Commission for Technology and Innovation of the Swiss Confederation and presented Plug ‘n’ Scope at the contests Apptitude Web Startup Challenge and at the Innovation for Health Competition of the World Innovation Day.
