DESCRIPTION:Prof. Yujia Zhang\nAbstract\nHydrogel iontronic devices can e
 mulate biological functions and communicate with living matter. However\, 
 the fabrication of miniature\, soft iontronic devices according to modular
  designs has not been achieved. In the lecture\, I will discuss the use of
  surfactant-supported assembly of freestanding microscale hydrogel droplet
 s\, termed dropletronics\, to construct various ionic power sources\, iont
 ronic modules\, circuits and biointerfaces. The tiny\, versatile dropletro
 nic devices enable a variety of biomedical applications\, including modula
 tion of brain organoids\, defibrillation and pacing of mouse hearts\, and 
 recording electrophysiological signals from sheets of human cardiomyocytes
 . I will also introduce some ongoing projects in the group and conclude by
  summarising the major challenges in the field and future directions.\n\nB
 iography\nYujia Zhang is a Tenure Track Assistant Professor of Electrical 
 and Microengineering at the School of Engineering at École Polytechnique 
 Fédérale de Lausanne (EPFL). He has led the Laboratory for Bio-Iontronic
 s (BION) since January 2025. A major interest of his laboratory is the dev
 elopment of iontronic biointerfaces and hybrid intelligent systems for bio
 medical detection and treatment. Recently\, he has pioneered the area of d
 ropletronics\, in which networks of microscale soft droplets function as v
 ersatile bioiontronic/bioelectronic devices.\nPrior to his appointment\, h
 e obtained his B.Sc. in electronics engineering from the University of Sci
 ence and Technology of China in 2016. Later\, he completed his PhD in biom
 edical engineering and MEMS/NEMS technology at the Shanghai Institute of M
 icrosystem and Information Technology\, Chinese Academy of Sciences\, foll
 owed by one year as a visiting PhD at Stony Brook University. In 2021\, Yu
 jia joined the Bayley group and later became an early-career research fell
 ow hosted in the Department of Chemistry at the University of Oxford.\n\nH
 e has received several awards so far:\n\n	Early-career Research Scientist 
 Representative\, UK Parliamentary & Scientific Committee (2023)\;\n	Excell
 ent Doctoral Dissertation\, Chinese Academy of Sciences (2021)\;\n	Special
  Prize of President Scholarship for Postgraduate Students\, Chinese Academ
