Our Research

Monolithically-Integrated Textile Electronics

Unlike conventional substrates, such as glass, PET or paper, textiles are 3D microscaffolds displaying roughness and texture on multiple length scales.
3D Scaffold

Conformal coating techniques are integral for directly growing nanostructured devices from textile substrates.
We perform a small variety of vapor phase polymerization reactions to create films of conjugated polymers inside a reduced-pressure hot wall reactor.
One such example is the oxidative chemical vapor deposition of EDOT to create PEDOT-Cl.
RVD

This process creates stable, conformal films of a conducting polymer--PEDOT-Cl, in this case-- on arbitrary substrates, including various prewoven textiles.

PEDOT-Cl coated Fabrics

We use this vapor-phase deposition method to transform ordinary textiles into functional electronic devices. Our approach also minimizes the tremendous water pollution caused by traditional textile processing.
Some of our products are described below.

Fabric / Thread Electrodes

We create highly-conductive fabrics and threads that are capable of acting as electrodes and interconnects while also being stable to sweat, laundering, ironing, stretching/tugging and rubbing.
Conductive Textiles

Smart Garments

We endeavor to seamlessly integrate electronic components, such as transistors, pressure sensors, heating elements, diodes, thermopiles, and supercapacitors, into garments by coating familiar threads and/or garments with judiciously-chosen polymer layers.
Garment Heart Rate Monitor

Activity-Tracking Textiles

We use a small selection of fabric-based pressure sensors to remotely detect joint motion, gait and posture during various activities.


Triboelectric Textiles

Energy Harvesting Textiles

We are exploring multiple integrative approaches to create solar fabrics and fabric-based thermopiles that preserve the breathability, pliability and durability of textiles.

Reactive Vapor Deposition

A suite of vapor-phase polymerization reactions performed inside reduced-pressure hot wall reactors, collectively termed RVD, are the enabling methods we use to build novel devices. In RVD, polymer films are formed directly on the substrate of interest as vapors of a chemical agent and precursor (or monomer) are introduced into an evacuated reactor chamber simultaneously. This method allows for conformal coating of rough surfaces, with features resolvable down to 100-200 nm. The modularity of RVD ensures that careful monomer choice will lead to the in situ film growth of a host of functional polymers displaying varied properties.

RVD

Our current toolbox of RVD reactors enable the deposition of chemically well-defined films of persistently-doped conducting polymers, semiconducting polymers, and poly(acrylates) on arbitrary substrates with micro- and nano-scale features. We are working to expand our toolbox to include n-type conjugated polymer films and conductive polyradical films.

Directing Crystal Orientation and Intermolecular Packing

Crystal orientation in organic thin films is one of the key parameters that determines interfacial energetics, absorption profiles and cross sections, exciton diffusion lengths, exciton dissociation efficiencies, and charge collection efficiencies. Significant excitonic and electronic changes, including huge modulations in absorption profiles, total %light absorbed, Fermi levels, band edge values and CT state energies can be observed when crystals are grown on different surfaces, such as ITO and graphene. Such changes can potentially increase the theoretical Voc expected for photovoltaic devices incorporating these templated films.

Subdiffraction Optical Lithography Enabled by Photochromes

Currently, nanomanufacturing is achieved via fast pattern-replication (nanoimprint lithography, optical-projection lithography, etc.) and is stymied by extremely slow pattern generation (scanning-electron-beam lithography). In other words, the time it takes to generate a new pattern is orders of magnitude longer than what it takes to simply replicate one.

Light offers significant advantages over charged particles for pattern generation. However, it suffers from one Achilles heel - diffraction. In the far field, the smallest focused spot that can be generated with light is limited to approximately half the wavelength.This, so called far-field diffraction limit or the Abbé limit, effectively prevents the use of long-wavelength photons (greater than 300nm) from patterning nanostructures less than 100 nm.

We have shown that optics, when combined with novel photochemistry, can result in deep sub-wavelength patterning with speeds that are far higher than with conventional approaches.

AMOL

Our idea is to record the nanoscale pattern in an ultra-thin or monolayer film comprised of photochromic molecules. These molecules undergo photoswitching between two isomeric forms, A and B. When isomer A absorbs a photon of wavelength 1, it turns into isomer B. When B absorbs photon of wavelength 2, it turns back to A. The binary nature of the switching process ensures that sub-diffraction-limited regions of B interspersed in A are formed.

In addition, we design the photochromic molecules such that B can be selectively converted in an irreversible manner to form C via a “locking” step, which allows us to create 3D patterns. These advances in pattern generation, when combined with continuous replication technologies such as roll-to-roll nanoimprint lithography can enable a new paradigm in high throughput top-down nanomanufacturing. In other words, organic photochromes can change the traditional process flow currently used to manufacture electronics!
