1. A system comprising:
- an absorbent pad for placement adjacent to a patient;
one or more sensors integrally formed with the absorbent pad and positioned to measure one or more voiding parameters;
an implantable stimulator that delivers electrical stimulation therapy to the patient; and
a processor that adjusts at least one stimulation parameter of the electrical stimulation therapy based on at least one voiding parameter measured by at least one of the sensors.

Abstract
The disclosure describes an absorbent pad worn by a patient that measures one or more urinary voiding parameters. One or more sensors that measure voiding parameters are integrally formed with the pad, e.g., interwoven with the absorbent pad material or positioned to form one or more sensor layers between layers of absorbent material. The sensors store measured parameters as information in a memory, e.g., as a log, locally or in a separate device. In some embodiments, the pad includes an electrical stimulator that provides stimulation therapy for urinary incontinence based on measured parameters.
