Research Statement

Gas Sensors

The focus of this research is on the development of a gas sensor toolkit for sensitive, selective and stable detection of undesirable gas species (e.g. NOx, SOx, CO, CO2) at high-temperatures. In2O3, NiO, Ga2O3 and Y-doped BaZrO3 for the detection of NOx, H2, CO and humidity, respectively have been investigated. Of primary importance were the effects of materials processing conditions on the gas sensitivity and response rate. Design, fabrication and integration of microhotplate structures with gas sensitive layers capable of functioning at temperatures greater than 500 °C were also performed.

Hydrogel Sensors for Metabolic Markers

The main objective of the research is to develop a sensor array that can monitor different biomarkers such as glucose, pH and pCO2 to help avoid long term diseases caused by irregularities in their levels. A sensing platform based on piezoresistive pressure transducers has been developed which is integrated with stimuli responsive polymers or smart hydrogels that act as the sensing element. Several in vitro experiments have been performed so far to establish stability and reproducibility of the sensor arrays to changes in glucose, ionic strength and pH concentrations in the environmental analyte. Response times to changes in concentrations have been found to be in the range if 5 to 10 minutes.

Integrated Neural Interfaces

The integrated neural interface program centered at the University of Utah is focused on developing chronically implantable, wireless, integrated neural interface devices based on the Utah electrode array. These devices may be used in the central or pheripherial nervous system for neural signal recording and/or stimulation to help people with motor or sensory impairments.

  • A novel glucose sensor is presented using smart hydrogels as biocompatible implantable sensing elements, which eliminates the need for implanted electronics and uses an external medical-grade ultrasound transducer for readout. The readout mechanism uses resonance absorption of ultrasound waves in glucose-sensitive hydrogels. In vivoglucose concentration changes in the interstitial fluid lead to swelling or deswelling of the gels, which changes the resonance behavior. The hydrogels are designed and shaped such as to exhibit specific mechanical resonance frequencies while remaining sonolucent to other frequencies. Thus, they allow conventional and continued ultrasound imaging, while yielding a sensing signal at specific frequencies that correlate with glucose concentration. The resonance frequencies can be tuned by changing the shape and mechanical properties of the gel structures, such as to …. Published, 09/20/2021.

  • Brain functions such as perception, motor control, learning, and memory arise from the coordinated activity of neuronal assemblies distributed across multiple brain regions. While major progress has been made in understanding the function of individual neurons, circuit interactions remain poorly understood. A fundamental obstacle to deciphering circuit interactions is the limited availability of research tools to observe and manipulate the activity of large, distributed neuronal populations in humans. Here we describe the development, validation, and dissemination of flexible, high-resolution, thin-film (TF) electrodes for recording neural activity in animals and humans. Published, 06/17/2021.
  • One-third of epilepsy patients suffer from medication-resistant seizures. While surgery to remove epileptogenic tissue helps some patients, 30-70% of patients continue to experience seizures following resection. Surgical outcomes may be improved with more accurate localization of epileptogenic tissue. We have previously developed novel thin-film, subdural electrode arrays with hundreds of microelectrodes over a 100-1,000 mm2area to enable high-resolution mapping of neural activity. Here we used these high-density arrays to study microscale properties of human epileptiform activity. We performed intraoperative micro-electrocorticographic recordings within epileptic cortex (the site of seizure onset and early spread) in nine patients with epilepsy. In two of these patients, we obtained recordings from cortical areas distal to the epileptic cortex. Additionally, we recorded from two non-epileptic patients with movement disorders undergoing deep brain stimulator implantation as non-epileptic tissue controls. A board-certified epileptologist identified microseizures, which resembled electrographic seizures normally observed with clinical macroelectrodes. Epileptic cortex exhibited a significantly higher microseizure rate (2.01 events/min) than non-epileptic cortex (0.01 events/min; permutation test, P=0.0068). Using spatial averaging to simulate recordings from larger electrode contacts, we found that the number of detected microseizures decreased rapidly with increasing contact diameter and decreasing contact density. In cases in which microseizures were spatially distributed across multiple channels, the approximate onset region was identified …. Published, 01/01/2021.
  • Smart hydrogel structures can be used as chemical sensing components to measure the changes in the environmental concentration of analytes of biomedical relevance. Sensing schemes using smart hydrogels rely on the transduction of the stimulated change of the hydrogels' physical properties into a usable signal. Recently, we reported on such a sensing technique employing resonance absorption of ultrasound in smart hydrogel microresonator structures as well as in a hydrogel sheet using medical ultrasound imaging as the transduction method. However, the mold-based fabrication process limited the possible geometries of the hydrogel structures, which resulted in a constrained response time. In this publication, we present an improved fast and cost-efficient fabrication process to create arrays of free-standing stimuli-responsive hydrogel pillars that can be used to address this challenge along with first ….
