The manuscript presents a miniature implantable pH sensor with ASK modulated wireless output together with a fully passive receiver circuit based on zero-bias Schottky diodes. This solution can be used as a basis in the development of in vivo calibrated electrostimulation therapy devices and for ambulatory pH monitoring.

Ambulatory pH monitoring of pathological reflux is an opportunity to observe the relationship between symptoms and exposure of the esophagus to acidic or ...

The application of high-frequency low-energetic stimulation can alleviate the symptoms of gastric dysmotility. In this research, a miniature, endoscopically implantable and wirelessly rechargeable device which is implanted into a submucosal pocket is presented. Successful both-way communication and stimulation control were achieved during an experiment on live pig.
