Nitrate is a commonly found nitrogen species in the environment, especially in agricultural regions. Since excessive nitrate accumulation has negative impacts on the environment, the quantitative monitoring of nitrate levels in the field is a critical component of precision agriculture. Researchers recently showed the application of plasticized polyvinyl chloride electrodes in conjunction with electrochemical...
The implantable CNT-based sensor is suggested to detect CSPGs which is main compositions of glial scar which inhibit the axonal regeneration after spinal cord injury. The suggested sensor is fabricated using spin-coated polyimide and patterned by MEMS process. Multiwalled CNT networks are formed by air spray method on the interdigitated sensor electrodes as the sensing element of CSPGs. The feasibility...
We fabricated a carbon nanotube (CNT)/ polydimethylsiloxane (PDMS) composite-based dry ECG electrode that can be readily connected to conventional ECG devices, and showed its long-term wearable monitoring capability and robustness to motion and sweat. While the dispersion of CNTs in PDMS is challenging, we optimized the process to disperse untreated CNTs within PDMS by mechanical force only. The electrical...
