Paper accepted in Nature Scientific Reports

After two years of collaboration with Dr Yeo from VCU , our work in swallowing sensing with skin-like electronics is finally accepted for publication in Scientific Reports, an open access Nature journal.  More information about the project can be found here.

We are currently working on a second project on wireless chewing monitoring through a mobile app! Watch this space for more updates.

Title: Soft Electronics Enabled Ergonomic Human-Computer Interaction for Swallowing Training

Abstract: We introduce a skin-friendly electronic system that enables human-computer interaction (HCI) for swallowing training in dysphagia rehabilitation. For an ergonomic HCI, we utilize a soft, highly compliant (“skin-like”) electrode, which addresses critical issues of an existing rigid and planar electrode combined with a problematic conductive electrolyte and adhesive pad. The skin-like electrode offers a highly conformal, user-comfortable interaction with the skin for long- term wearable, high-fidelity recording of swallowing electromyograms on the chin. Mechanics modeling and experimental quantification captures the ultra-elastic mechanical characteristics of an open mesh microstructured sensor, conjugated with an elastomeric membrane. Systematic in vivo studies investigate the functionality of the soft electronics for HCI-enabled swallowing training, which includes the application of a biofeedback system to detect swallowing behavior. The collection of results demonstrates clinical feasibility of the ergonomic electronics in HCI- driven rehabilitation for patients with swallowing disorders.
