Agnirva Space Premier League - Expedition #30774: Power from Pressure: Piezoelectric Actuators Tested in Space

Led by Dr. Nozomu Kogiso of Osaka Prefecture University, the ExHAM-Piezo Electric Actuator Characteristic Experiments explored the performance of piezoelectric actuators in space. These devices convert mechanical stress into electrical energy—or vice versa—making them useful for precision movement and energy harvesting.

Mounted on the ISS’s ExHAM facility, the actuators were tested across multiple expeditions to evaluate how microgravity, temperature swings, and cosmic radiation affect their mechanical and electrical performance. This experiment helps engineers understand whether piezoelectric systems could reliably operate in satellites, robotic arms, or spacecraft sensors.

Such actuators could revolutionize spacecraft design, allowing for lightweight, efficient components in mobility, control, and even power generation. If they remain stable in space, they could become essential tools for the next generation of exploration systems.
