感知神经递质在研究神经通路和神经系统疾病中至关重要。提出了一种集成装置，其结合了恒电位仪和功率收集和遥测模块。恒电位仪具有16个通道，具有从微安到皮安的多个量程。无线模块能够通过感应耦合线圈收集电力，并使用相同的链路向恒电位仪传输数据和从恒电位仪传输数据。一个集成的原型是在CMOS工艺制造，并进行了实验表征。测试结果表明，在500 pA和4 nA恒电位仪电流标度下，射频供电引入的噪声水平分别为0.42%和0.18%。采用碳纤维传感器对体外多巴胺浓度进行实时多通道采集
Sensing neurotransmitters is critical in studying neural pathways and neurological disorders. An integrated device is presented which incorporates a potentiostat and a power harvesting and telemetry module. The potentiostat features 16 channels with multiple scales from microamperes to picoamperes. The wireless module is able to harvest power through inductively coupled coils and uses the same link to transmit data to and from the potentiostat. An integrated prototype is fabricated in CMOS technology, and experimentally characterized. Test results show RF powering introduces noise levels of 0.42 % and 0.18 % on potentiostat current scales of 500pA and 4nA respectively. Real-time multi-channel acquisition of dopamine concentration in vitro is performed with carbon fiber sensors
