# Key Insights from #hplusroadmap IRC Discussion

• Participants discussed piezoelectric properties in human skin, noting that dermis piezoelectricity comes from collagen networks while epidermis piezoelectricity originates from keratin-like tonofibrils, with the highest coefficients found in the horny layer.

• The channel featured extensive sharing of system dynamics modeling resources, including bond graphs and extended bond graphs (EBG) for electromagnetic and electromechanical systems, with specific textbook recommendations by Beaman & Paynter, Brown, Karnopp, and others.

• Microfluidics technology was highlighted as a potential replacement for manual pipetting in labs, with a substantial archive (585MB) of microfluidics papers being shared among participants.

• The conversation included technical neuroscience details, noting that human axons can extend several feet (as in the sciatic nerve), while squid giant axons can reach 1mm in diameter but lack myelination.

• Participants engaged in philosophical debates about intellectual property rights, arguing that the current system creates "artificial lack" in digital content, with some artists experimenting with free distribution plus donation models.

• The discussion referenced the Pirate Party's political success in Sweden (7.1% of votes), shifting public discourse from "free downloading" to broader issues of privacy and copyright reform.
