D espite widely used technologies that can provide power to large-scale targ ets\, such as wired energy supplies from batteries or wireless energy tran sduction\, a need to efficiently modulate cells and tissues on the microsc ale is still pressing. The ideal miniaturized power source should be bioco mpatible\, mechanically flexible\, and able to generate an ionic current f or biological modulation—iontronic devices\, instead of using electron f low as in conventional electronic devices. In this seminar\, the presenter will discuss his research on miniature soft batteries based on the lipid- supported assembly of hydrogel droplet networks. By exploiting biocompatib le polymers and protein modifications\, the droplet batteries feature trig gerable activation\, high energy density\, and multifunctionality. Applica tions include the modulation of 3D neural microtissues and the defibrillat ion of ex vivo mouse hearts. Moving a step forward\, the hydrogel droplets can also incorporate other synthetic and biological parts and could integ rate functions of the embedded materials\, such as logic control and thera peutics delivery\, etc. Ultimately\, by 3D printing synthetic tissues comp osed of various modules together\, the droplet networks become iontronic s ystems that can express collaborative properties and enable interactive co mmunication with biology. The droplet-based system will provide an alterna tive strategy\, in parallel to bioelectronic medicine\, to be used as bioi ontronic medicine for human-machine interfaces and medical treatments.\n\n Short Bio\nDr Yujia Zhang is a postdoctoral research associate in the Bayl ey group at the University of Oxford. He graduated in 2016 with a BSc in E lectronics and Information Science and Technology from the University of S cience and Technology of China. Later\, he completed a DPhil in biomedical engineering and MEMS/NEMS technology at the Shanghai Institute of Microsy stem and Information Technology (Chinese Academy of Sciences)\, followed b y one year of being a visiting scholar at Stony Brook University (The Stat e University of New York). In 2021\, Yujia started his postdoctoral resear ch at the Bayley group with a focus on the development of multifunctional iontronic synthetic tissues for biotic interfaces and soft implants. He re ceived the Chinese Academy of Sciences Presidential Scholarship (Special P rize) in 2020 and was selected by the UK Parliamentary & Scientific Commit tee as a representative early-career scientist in 2023.\n  LOCATION:BM 5202 https://plan.epfl.ch/?room==BM%205202 https://epfl.zoom.u s/j/65685816024 STATUS:CONFIRMED END:VEVENT END:VCALENDAR
