Abstract The dissemination of sensors is key to realizing a sustainable, ‘intelligent’ world, where everyday objects and environments are equipped with sensing capabilities advance the sustainability quality our lives—e.g. via smart homes, cities, healthcare, logistics, Industry 4.0, precision agriculture. realization full potential these applications critically depends on availability easy-to-make, low-cost sensor technologies. Sensors based printable electronic materials offer ideal...
Abstract Low‐cost biosensors that can rapidly and widely monitor plant nutritional levels will be critical for better understanding health improving precision agriculture decision making. In this work, fully printed ion‐selective organic electrochemical transistors (OECTs) detect macronutrient concentrations in whole sap are described. Potassium, the most concentrated cation majority of plants, is selected as target analyte it plays a role growth development. The ion sensors demonstrate high...
Abstract Printable and wearable plant sensors offer an approach for collecting critical environmental data at high spatial resolution to understand conditions aid land management practices. Here, screen printed capacitive devices that can measure relative humidity (RH) directly the plant‐environment interface, are demonstrated in ultra‐thin (<6 µm) form factor. Using printing a temporary tattoo transfer process, simple technique is established to: 1) enclose electronic features between...
Abstract The chemical composition of growing media is a key factor for plant growth, impacting agricultural yield and sustainability. However, there lack affordable sensors ubiquitous nutrient ion monitoring in applications. This work investigates using fully printed ion‐sensor arrays to measure the concentrations nitrate, ammonium, potassium mixed‐electrolyte media. Ion sensor composed ion‐selective electrodes silver‐silver chloride (Ag/AgCl) reference electrode are fabricated characterized...
We use a random forest (RF) model to predict the critical cooling rate (RC) for glass formation of various alloys from features their constituent elements. The RF was trained on database that integrates multiple sources direct and indirect RC data metallic glasses expand directly measured less than 100 values training set over 2000 values. error 5-fold cross-validation (CV) is 0.66 orders magnitude in K/s. leave-out-one-group CV alloy system groups 0.59 log units K/s when target constituents...
Abstract A key challenge in bioelectronics is to establish and improve the interface between electronic devices living tissues, enabling a direct assessment of biological systems. Sensors integrated with plant tissue can provide valuable information about itself as well surrounding environment, including air soil quality. An obstacle developing interfaces mitigating formation fibrotic which hinder continuous accurate sensor operation over extended timeframes. Electronic systems that utilize...
Abstract In this work, we present a novel method for integrating printed electronic materials with biocompatible cryogels to form stable, implantable hydrogel-based bioelectronic devices that show stable long-term operation inside plant tissue. The gels can be customized provide various functionalities, including electrodes and organic electrochemical transistors (OECT). These inkjet cryogel-based exhibit high electrical conductivity embedded conductive polymer traces (up 350 S/cm),...
