CDT student awarded Best Poster Prize at prestigious conference

One of our students Minghao Zhao recently attended the 10th annual Innovations in Large-Area Electronics Conference (innoLAE 2024) which took place at Magdalene College Cambridge.  Minghao was awarded the prize for his poster titled “Inkjet-printed sensors based on 2-dimensional ReS2”

Minghao described the project as “Heterostructures are the basic structures of many two-dimensional-materials-based devices. By combining the electrochemical exfoliation (ECE) method and inkjet printing technology, we are able to achieve highly efficient device fabrication to minimize the waste of material and build devices on various substrates. We successfully produced high-quality ReS2 nanosheets via ECE methods and fabricated flexible humidity sensors and photodetector with fully inkjet-printed heterostructures. The highest photoresponsivity is ~500 mA/W, measured at 633 nm. 

"The device also shows a fast response time of ~6 ms. The humidity sensors show fast response (0.4 s) and recovery (0.32 s) time, little hysteresis, and the highest sensitivity of 33.2 pF/%RH in the range of 60-94%. By integrating the RH sensor onto a face mask, we successfully monitored human breathing pattern under different circumstances, confirming the great potential of inkjet printing technology for wearable health monitoring applications.”

Congratulations to Minghao on his award!
