| Abstract Scope |
Printed electronics can enable novel sensing platforms which can benefit from the incorporation of nanomaterial thin films. Aerosol jet printing is an ideal candidate for depositing spatially patterned nanomaterial thin films with a high degree of morphological control. This talk will first focus on optical methods to quantify the in-flight droplet characteristics of aerosol jet printing, which enable a predictive feedback parameter. Next, I will discuss two sensing technologies which benefit from the morphological control achieved through aerosol jet printing, including self-powered triboelectric force transducers and electrochemical nutrient sensors. The self-powered force sensors utilize micro-scale textured silver nanoparticle electrodes to optimize the static charge transfer within sliding mode triboelectric force transducers. The soil nutrient sensors are optimized through the introduction of a printable graphene ink to minimize the sensor response time. The talk will conclude with a discussion regarding the outlook for printable nanomaterial-based sensing technologies. |
