Optimizing extrusion parameters for stretchable fibers and wearable sensors

The Koh Lab has recently completed a custom-built mini extruder for making thermoplastic elastomer fibers. With this extruder, we can make stretchable fibers either as 3D printing substrates or as dielectric materials for wearable pressure sensors. In order to optimize the fibers we will explore various metal and ceramic fillers and loadings. The student part of this project will not only optimize the parameters needed to optimally extrude fibers with varying thicknesses but will also learn to characterize the mechanical and electrical properties of the fibers and thermoplastic materials independently as well as, ideally, in a stretchable device....

Developing capacitive pressure sensors for the capture of breath information via voice and instrument

The Koh Lab has a significant depth of experience creating novel dielectric materials for capacitive pressure sensors. So far, our work has focused on high loads such as those you may expect under the foot from walking. In this project, we look to expand our usage of capacitive pressure sensors to capture information about breath in two unique ways. First, we will put capacitive pressure sensors in instruments to record pressure changes from the vibrations caused by breathing. Second, we will develop pressure sensors to be worn on the torso to quantify breathing patterns of vocal students in order to better quantify the methods needed to properly control breath with the long term goal of developing training programs for at home therapy ...

biomedical and environmental sensors

Dr. Cheng is looking for motivated undergraduate students to join his group. The students will participate in several projects funded by NSF, GLPF and UA. As an example, his group is developing new implantable material, sensors and machine learning algorithms in order to remotely monitor people with disabilities. The students should be familiar with engineering principles, programming and problem solving....

3D modeling, CNC machining and extrusion molding

I am looking for a student who is interested in learning 3D modeling, CNC machining and extrusion molding. My lab has a very nice CNC machine, Tormach 440 (see here https://www.tormach.com/pcnc-440/). I plan to utilize this CNC machine to make plastic enclosures for the small wearable sensors. First, 3D models of enclosures and molds to make these enclosures need to be designed in Fusion 360 software. Then the molds need to be machined out of wax and tested. When the molds are fully tested, we will need to machine them from aluminum. The machined molds then will be used with a plastic extrusion machine to make enclosures. This is a rather involved project but a fun learning experience for anyone interested in advanced manufacturing....
