On July 3, 2024, the Faculty of Mechanical and Aerospace Engineering (FTMD) at ITB held a public lecture featuring Arief Suriadi Budiman, Ph.D., an FTMD ITB alumnus who is currently an academia in the Department of Manufacturing, Materials, and Renewable Energy, and the Director of the Oregon Renewable Energy Center (OREC) at the Oregon Institute of Technology. In the lecture, Dr. Budiman discussed the topic “Generative Design and Additive Manufacturing of Flexible Lattice-Based Conductors for Electronic Skin and Other Flexible Biomedical Devices.”

Dr. Arief Budiman elaborated on the supergliding solid-solid effect in Cu/Nb nanolayers, which shows great potential for next-generation flexible/metallic conductor technology. This technology offers superior mechanical and electrical fatigue properties. The research findings presented included in situ fracture at the nanoscale, finite element modeling and simulation, and how the supergliding effect relates to data science for developing flexible conductors with superior fatigue properties.

Furthermore, Dr. Arief Budiman provided an overview of additive manufacturing (AM) that can be implemented in designs using lattice structures. This design allows for weight and cost savings by using metal materials without compromising structural strength, which is crucial for applications in mechanical engineering, aerospace, and biomedical fields.

The latest research project presented by Dr. Budiman involved the additive manufacturing (AM) of Cu interconnects based on lattice structures using a blue diode laser. This technology enables the production of flexible and stretchable Cu-based conductors used in various applications such as electronic skin, flexible electronic devices like flexible batteries and wearable devices, as well as wearable biomedical devices. Dr. Budiman also highlighted how the use of blue diode lasers in AM allows for the creation of unique and complex 3D shapes of Cu conductors, opening new opportunities for innovation in various future technology fields.

This public lecture provided deep insights into the potential of additive manufacturing and generative design technology in creating advanced flexible conductors for future applications, particularly in electronics and biomedicine.
