This Faculty Early Career Development (CAREER) Program award focuses on the development of a novel active material formed from integrating the ionic properties of a bio-derived membrane and a conducting polymer membrane. The scientific goal of this project is the development of a hybrid membrane that can respond to low power electrical signal or low concentration chemical trigger and perform electromechanical work using ambient chemical gradients. This hybrid membrane, referred to as Bio-derived Ionic Transistor (BIT) functions as the fundamental unit in sensing and actuation systems. A BIT device comprising a conducting polymer and a bio-derived membrane (BLM with proteins) will be fabricated, characterized using a coupled model and optimized into a robust transistor. The scientific goal of this research proposal will be achieved by addressing the following questions: What is/are the (i) limiting conditions (geometrical, chemoelectrical, mechanical) for ion transport, (ii) relationship between the output, gating signal and input (static, dynamic), (iii) open-loop and closed-loop operation (transfer function, sensitivity, disturbance rejection, stability and performance limitation) and (iv) fabrication constraints and scalability.If successful, this CAREER research project will lead to the development of a robust real-time sensing array constructed using BIT devices that can detect chemical and bioelectrical signals using commercially available proteins and be applicable in healthcare, national defense and homeland security. This project will also lead to the development of an artificial muscle using the chemomechanical properties of the BIT device. This CAREER award will enable the PI to build an inter-disciplinary research program in Polymer Mechatronic Materials, promote participation of women in engineering, integrate this research work in to undergraduate and graduate curriculum at Virginia Commonwealth University through Active Learning and disseminate knowledge in this field to the general public and school students in the Commonwealth through continuous engagements with the Science Museum of Virginia at Richmond, Virginia.

该教师早期职业发展（职业）计划奖的重点是开发一种新型的活跃材料，该材料是由整合生物衍生的膜和指导聚合物膜的离子特性而形成的。 该项目的科学目标是开发杂交膜，该杂交膜可以响应低功率电信号或低浓度化学扳机，并使用环境化学梯度进行机电工作。该混合膜被称为生物衍生的离子晶体管（BIT）作为感应和驱动系统的基本单位。 将制造一个包括导电聚合物和生物衍生的膜（带蛋白质的BLM）的位设备，使用耦合模型进行表征，并优化为健壮的晶体管。 The scientific goal of this research proposal will be achieved by addressing the following questions: What is/are the (i) limiting conditions (geometrical, chemoelectrical, mechanical) for ion transport, (ii) relationship between the output, gating signal and input (static, dynamic), (iii) open-loop and closed-loop operation (transfer function, sensitivity, disturbance rejection, stability and performance limitation) and (iv) fabrication constraints如果成功的话，这个职业研究项目将导致使用位设备构建的健壮实时感测阵列的开发，该阵列可以使用可使用市售蛋白质检测化学和生物电信号，并适用于医疗保健，国防和国土安全。该项目还将使用BIT设备的化学力学特性导致人造肌肉的发展。该职业奖将使PI能够在聚合物机电材料中构建一项跨学科研究计划，促进妇女参与工程学，将这项研究的工作整合到弗吉尼亚州英联邦大学的本科和研究生课程，通过积极学习，并通过该领域的公共和学校学生在英联邦的virginia中通过不断地参与其中的Ricmond offirgondia，并将其在该领域的公共和学校学生中将知识分发到该领域的知识。
