Zebrafish have proven to be a crucial model for biological elucidations, especially heart-disease studies, owing to their remarkable regeneration capacity. Other than conventional methods, monitoring of electrocardiogram (ECG) has shown promising results recently; however, experiments were usually carried out with sedated fish, resulting in affected signals. In this work, wireless power transfer (WPT)...
In this work, we developed a dual-sensor system to monitor the symptoms in gastroesophageal reflux disease (GERD). The system consists of an implantable transponder and an external reader. The passive telemetry for signal transduction is based on an inductive link between two coil antennas. The reader supplies radio frequency power, obtains and stores the backscattered sensory data. The dual-sensor...
A wireless strain sensor system has been designed to monitor the bladder volume in patients suffering from urinary incontinence. An interdigitated capacitive (IDC) strain sensor was micro-machined from a 127-µm thick brass shim with a laser system, followed by an encapsulation process to package the sensor in elastic polydimethylsiloxane (PDMS). A proof-of-concept passive telemetry platform was developed...
In this presentation, we will review and discuss recent advances in the research of wireless telemetry for medical applications in our group at UT-Arlington, particularly those based on a similar platform for in vivo monitoring of physiological parameters. System for recording ECoG signals in brain, recording in vivo gastric myoelectric activities in stomach, sensing in vivo strain variations in bladder,...
