Continuing from previous work, a paper has just been published Open Access in Communications Materials, entitled “Biocompatible low-voltage electrothermal actuators with biological operational temperature range“. This new study is authored by Adéla Slavíková, Benjamin C. Baker, Marcos Villeda-Hernandez, undergraduate contributors Annabel Coekin and Julia Kwasniewska, collaborators from NHS and Bristol Medical School within the emPOWER project, and Charl Faul.

This study presents a low-voltage (3.6 V) electrothermal actuator, Bio35, that operates at mild hyperthermic temperatures (38.9 °C). Bio35 features facile synthesis, high chemical stability, excellent cyclic actuation performance, and non-cytoxicity. Two systems have been demonstrated: a simple gripper and a sphincter-like valve, showcasing Bio35‘s potential for use in treating conditions like urinary incontinence, where precise, muscle-like actuation is critical for function.
