Enhanced electrogastrography: A realistic way to salvage a promise that was never kept?

Figure 2 Breakdown of the enhanced electrogastrography gastric retentive pill. The oscillator circuit was first sealed into the assembled capsule, and added to superabsorbent granules held in a liquid-permeable mesh. This was inserted into a dissolvable pill, which completely disintegrated in the stomach after 10 min, allowing the granules to swell. A mm scale is provided on the left of the image. 1: Oscillator circuit; 2: Capsule body; 3: Assembled capsule; 4; Superabsorbent granules; 5: Capsule and granules inside a liquid-permeable mesh; 6: Dissolvable pill containing the mesh enclosed capsule; 7: Enhanced electrogastrography gastric retentive pill; 8: Pill expanded in water; 9: Test dish.
