Ma’s research group is dedicated to cutting-edge interdisciplinary research in organic bio-iontronics, with the core objective of developing next-generation flexible intelligent systems that are high-performance, multifunctional, and biocompatible. Our research focuses on the following five closely related directions to build a comprehensive research chain spanning from fundamental materials and device physics to system integration:

1.High-Performance Organic Photovoltaics (OPV): We conduct in-depth research on the morphology control mechanisms of organic photovoltaic materials, aiming to enhance energy conversion efficiency and stability. We place special emphasis on water-processable photovoltaic systems, ultra-flexible and ultra-lightweight devices, and large-area manufacturing processes, with the goal of providing stable and sustainable energy supply units for flexible electronic systems.

2. Smart Organic Electrochemical Transistors (OECT): We explore the immense potential of OECTs in multi-modal biosensing, in-memory computing architectures, and high-density array integration. The core goal is to realize flexible intelligent chips that integrate sensing, memory, and computing, providing a key hardware platform for real-time, in-situ information perception and processing.

3.Organic Neuroelectronic Materials: We are committed to developing organic neuroelectronic materials with mixed ionic/electronic conduction properties, focusing on their biomimetic synaptic plasticity, low-energy neural signal transmission, and processing mechanisms. By constructing flexible interfaces compatible with biological neural systems, we aim to develop high-performance devices for neuromorphic computing, brain-computer interfaces, and artificial neurons, laying the material foundation for next-generation bio-intelligent integrated systems.

4.Multifunctional Hydrogel Electronic Materials: We design and develop novel bio-interfacial hydrogels, nanoparticle composite hydrogels, and other advanced materials. These materials combine excellent biocompatibility, ionic/electronic conduction properties, and responsiveness to external stimuli, enabling the construction of efficient and safe bio-electronic interfaces and providing critical material support for implantable/wearable devices.

5.Advanced Photoelectrodes and Photoelectric Mechanisms: We focus on the photoelectric conversion mechanisms of organic semiconductor photoelectrodes, the design of novel materials, and the regulation of device photoelectric behavior. We conduct in-depth studies of novel physical processes and develop efficient patterning technologies to provide theoretical and technical foundations for photoelectric devices (such as photodetectors and optical modulators) and optically controlled bio-interfaces.
