Abstract: A disposable article to be fitted to a wearer. The disposable article preferably comprises a sensor operatively connected to the article. The sensor is adapted to detect electrical activity in the wearer's smooth colonic muscles, abdominal muscles or the muscles surrounding the bladder or rectum which correlates to an impending elimination of bodily waste and to provide a signal to the wearer, a caregiver or an element of the article of the impending event.

Abstract: A catheter for sensing vertebrate conditions has plural piezoresistive sensors directly electrically coupled to discrete application specific integrated circuits. A mechano-responsive element is in pressure sensitive relationship with the piezoresistive sensor to act as a transfer medium through which vertebrate conditions such as pressure, temperature, water, glucose, and pH are transferred. Each integrated circuit is electrically coupled to a data acquisition system with monolithic circuitry in order to amplify and multiplex signals from multiple sensors.
