“…Jiranusornkul et al fabricated an inkjet printed piezoresistive pressure sensor on commercial filter paper by water mask method. [176] The sensor comprised two main components; a base made of polystyrene (PS) and a paper diaphragm with carbon piezoresistor on the edge. The resistance of the sensor changed when the diaphragm was subjected to external pressure.…”

Printing processes can be broadly classified into "contact" and "non-contact" printing. In contact printing, the ink is transferred directly from a patterned medium (engraved roller or stencil) onto a substrate, while in non-contact printing the ink droplets are ejected from a series of nozzles on the intended surface. [9] Offset, flexography, gravure, and screen printing are among the most common contact printing methods, while jet-printing processes constitute noncontact counterpart. Jet-printing involves a series of computer-controlled pattern reproduction techniques, which can be subdivided into inkjet, aerosol-jet, and electrohydrodynamic-jet printing. In these techniques, the ink is deposited in the form of droplets hence named "droplet-based" printing. Inkjet is a wellestablished technology, which is now finding its way in to industries, [10] while aerosol jet is a relatively new technology developed for printing on non-planar substrates. The first prototype of electrohydrodynamic jet printing was patented for graphical patterning, but later on altered for high-resolution electronic printing in nanometer scale. [11] Flexible physical sensors fabricated by printing techniques are revolutionizing healthcare sector by befitting portable health watching and remote medical solutions. [12] These devices not only enable long-term tracking of physiological signals, but also enormously assist in delocalization of medical services from hospitals to homes. Flexible physical biosensors are widely used to record various biophysical signals such as pulse rate, body temperature, vocal fold vibrations, skeletal muscle contractions, closure of heart valves, breath rate, and movements in the gastrointestinal tract. [13] However current devices fabricated by printing techniques, suffer from low sensitivity and poor repeatability, therefore there is room for huge improvement in this field through specially formulated inks and printing process control. [14] Herein, we present a comprehensive discussion on basics of droplet-based printing techniques (inkjet, aerosol jet, and electrohydrodynamic jet), followed by an in-depth review of metal, carbon, polymer, and ceramic functional inks. We also delve into various post-processing (sintering) methods used to enable flexible devices on substrates with low thermal resistance. The field of flexible devices is vast, and the focus of this paper is on flexible physical sensors fabricated through droplet-based Printed electronics (PE) is an emerging technology that uses functional inks to print electrical components and circuits on variety of substrates. This technology has opened up new possibilities to fabricate flexible, bendable, and form-fitting devices at low-cost and fast speed. There are different printing technologies in use, among which droplet-based techniques are of great interest as they provide the possibility of printing computer-controlled design patterns with high resolution, and greater production flexibility. Nanomaterial inks form the heart of this technology, enablin...

“…Triboelectric nanogenerators (TENGs) based on the triboelectric effect and electrostatic induction have been extensively investigated for their ability to effectively harvest a variety of mechanical energies such as wind, water flow, and human motion and convert these energies into electricity. , Cellulose paper, mainly composed of cellulose fibers, has been extensively applied in supercapacitors, solar cells, nanogenerators, and sensors because it has advantages of flexibility, renewability, biocompatibility, biodegradability, wide accessibility, and environmental friendliness compared to other polymer-based materials. − Additionally, cellulose paper is an electron-donating material in the triboelectric series because it easily loses electrons and charges positively by contacting periodically with electron-accepting materials, such as polytetrafluoroethylene, poly(dimethylsiloxane) (PDMS), and polyvinylidene fluoride. − Cellulose paper-based TENGs (CPTENGs) have been fabricated successfully by using tissue paper, print paper, crepe paper, hard paper, and paper card and have a wide range of applications like electronic devices, electrochemistry, and sensors. − Although these research studies have exhibited various CPTENGs, there still remain a number of challenges to fabricate high-output performance and novel-structure CPTENGs via a facile preparation process.…”

Cellulose paper-based triboelectric nanogenerators (CPTENGs) have gained considerable attention because they are low-cost, lightweight, flexible, and environmentally friendly. However, the poor triboelectric property and hydrophobicity of cellulose paper still limit the development of high-performance CPTENGs. In this work, octadecylamine (ODA) has been introduced onto cellulose fibers to prepare hydrophobic cellulose paper (HCP) by means of polydopamine (PDA) which can react with ODA and hydrogen bond with cellulose. Benefiting from the ODA and PDA co-modification, HCP exhibits excellent triboelectric property, surface roughness, and hydrophobicity; moreover, the HCP exhibits remarkable resistance to acids and alkalis. In addition, an HCPbased TENG (HCPTENG) shows an open-circuit voltage (V OC ) of 237.8 V and a short-circuit current (I SC ) of 4.2 μA, which are higher than those of the most of cellulose paper-based TENGs. More importantly, the HCPTENG shows great output performance stability when treated with water, acids, and alkalis. The HCPTENG with a retractable and collapsible lantern structure can harvest energy from human movement and detect the foot motion like walking and running and hand flapping.

“…Jiranusornkul et al fabricated a paper-based piezoresistive pressure sensor has been fabricated through piezoelectric DoD [380]. Using an inkjet-printed water pattern, nonpolar solutions can be precisely fabricated with high precision as the water acts as a protective mask allowing octadecyltrichlorosilane to absorb only on the non-patterned areas.…”

Diagnostic biomolecule quantification in healthcare relies on effective but centralized laboratory testing procedures. However, as the need for testing rapidly grows, the current process is struggling to meet the demand. Rapid point-of-contact analysis devices are not capable of non-invasive quantification of small, dilute molecules such as steroid hormones in saliva. Current literature bioquantification devices suffer from drawbacks such as short shelf life, high intra-device variability, sample matrix effects, material incompatibilities, high-cost fabrication and data collection that rely on laboratory conditions and processes. This body of work took our organic electrolyte gated field effect transistor (OEGFET), a novel biosensor architecture, and developed it into a feasible platform for real-world biomolecule quantification applications.1-iv | P a g e For all of the papers presented in this work I was listed as the primary author as I contributed to study conception and design, device fabrication, device testing, analysis and interpretation of results, and manuscript draft preparation. My supervisor Prof. R. Prakash contributed to study conception and design, result interpretation, and manuscript preparation for all papers.Additional Contributions: J1. Dr. S. Bebe fabricated the top gate surfaces and helped with editing the manuscript draft. J2. Dr. R. Amache developed the bio-gel fabrication process, fabricated the bio-gel EDLC capacitors and helped with manuscript editing. Dr. S. Bebe also helped with manuscript preparation and fabricated the device top gates. J3. I also redesigned the OEGFET devices into a flexible format including establishing an APTES immobilization process that would be suitable for Kapton and safe to perform in our cleanroom. J4. I also optimized the new models and designed their parameter extraction processes. J5. I also redesigned the APTES process to prevent delamination. Prof. R. Prakash also acquired ethics board approval for the collection and testing of human saliva. J6. B. Gamero and I decided on the current shunt method of data collection for the OEGFET, and I wrote the software for the OEGFET data collection with the board. B.
