The inner workings of the intestines, in which the body and microbiome intersect to influence
gut function and systemic health, remain elusive. Carbon dioxide, hydrogen, methane and …

Enzymatic activities are important for normal physiological processes and are also critical
regulatory mechanisms for many pathologies. Identifying the enzyme activities in vivo has …

We hypothesized that ingested warm fluids could act as triggers for biomedical devices. We
investigated heat dissipation throughout the upper gastrointestinal (GI) tract by administering …

Biodegradable electronic devices are able to break down into benign residues after their
service life, which may effectively alleviate the environmental impacts as a consequence of …

Bioelectronic devices residing within the human body often rely on wireless signals to
interact with the external world. The transmission of wireless signals from the body, however …

Printed Electronics (PE) has a rapidly growing market, thus, the counterfeiting/overbuilding
of PE components is anticipated to grow. The common solution for the counterfeiting is …

A gastric acid battery and its charge storage in a capacitor are a simple and safe method to
provide a power source to an ingestible device. For that method, the electromotive force of …

Macromolecule drugs such as insulin have transformed our capacity to effectively treat
diseases; however, their rapid degradation and poor absorption in the gastrointestinal (GI) …

Biocompatible microbatteries, where the gastric fluid acts as an electrolyte, have shown
promise as energy sources for ingestible electronic devices. Because gastic fluid is the …

Non-invasive microsystems are emerging as a means to address diagnostics challenges in
healthcare due to the potential to retrieve information at the source and in a personalized …
