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

Figure 1 The oscillator circuit, printed circuit board layout, and enhanced electrogastrography capsule body. Dimensions of the circuit board were 10 mm × 6 mm, which allowed it to fit inside the capsule body that had dimensions 19 mm × 10 mm. Size of the board was constrained by component choice, as well as the need for swelling polymers surrounding the capsule body.
