This week was all about sourcing materials. We sat down with our mentor, Marco, who gave us highly practical prototyping advice regarding battery life, form factor, 3D printing, and overall device reliability. Following a hands-on seminar bridging hardware and software, we met up with Professor Hugo to officially acquire our Electrodermal Activity (EDA) sensor. To validate the demand for our solution, we launched a public survey exploring the primary reasons people avoid seeking psychological help, data that will directly fuel our upcoming pitch decks.
