• To explore the potential of piezoelectric materials for sensing and actuating organoids.
• To establish a proof of concept for electrical stimulation of organoids using ultrasound.

Main Methods:

• Human pluripotent stem cells were differentiated into spheroids on piezoelectric nanofiber scaffolds using the HIO protocol.
• Organoids were cultured and characterized for morphology, structure, and patterning.
• Ultrasound stimulation was applied to HIOs cultured on nanofiber scaffolds to assess cellular response.

Main Results:

• Piezoelectric nanofibers accelerated spheroid formation by 3 days compared to conventional methods.
• HIOs grown on scaffolds showed normal development, transplantability, and tissue organization.
• Ultrasound stimulation of HIOs on scaffolds increased cellular proliferation without detrimental effects.

Conclusions:

• Piezoelectric nanofibers are compatible with HIO generation and promote accelerated development.
