Linköpings universitet presenterar den första organiska elektrokemiska kardiomyocyten (OECM) — en analog hårdvaruimplementering av hjärtcellens elektriska beteende. Istället för rent simuleringsbaserad kardiak modellering möjliggör OECM:n nu direktemulering av ventrikelbeteende i fasta material. Komponenten återger tre samtidiga jonströmmar med rätt tidskonstanter: snabb natrium, långsam kalcium och beroende kaliumströmsignal. Detta genererar verklighetsnära actionpotentialer med korrekt refraktärperiod och svarar på elektrisk och kemisk stimulering. Systemet synkroniserar också med signaler från levande hjärtceller. Forskningen samlar Swedish organelektronik-kompetens med italienska och brittiska kardiovaskulär expertis. För produktchefer och investerare öppnas en väg från simulering mot embeddade kardiak-hårdvara för validering, diagnostik och implantatstyrning — med närmaste kommersiella horisont flera år bort.
