Active on-patient sensor, method and system

Apparatus to sense a condition adjacent a human body, comprising:

• a sensor to sense a condition adjacent a human body, wherein the condition is at least one from the group consisting of a pressure occurring in response to weight of the human body against a support and moisture occurring from incontinence;
• a transmitter configured to operatively associate with the sensor to transmit a signal digitally encoded with a unique identifier responsive to the sensor, the transmitter including an antenna;
• and
• a flexible substrate having the antenna disposed thereon and connected with the sensor and transmitter in low profile enabling disposition of the apparatus adjacent a human body.

Apparatus to sense a condition adjacent a human body, comprising:

• a sensor to sense a condition adjacent a human body, wherein the condition is at least one from the group consisting of a pressure occurring in response to weight of the human body against a support and moisture occurring from enuresis;
• a transmitter configured to operatively cooperate with the sensor to transmit a signal responsive to the sensor;
• a power supply for providing electricity to operate to the sensor and the transmitter, wherein the power supply includes a removable insulator film and a battery having a terminal initially electrically isolated from the sensor and transmitter by the insulator film such that the apparatus is energized by the battery upon pulling the insulator film out;
• and
• a flexible printed circuit substrate having at least the transmitter and the power supply mounted thereon in low profile enabling disposition of the apparatus adjacent a human body.

A method of sensing a condition adjacent a human body, comprising:

• disposing in low profile adjacent a human body, by adhering to skin of the human body or by putting a diaper on the human body, apparatus to sense a condition adjacent the human body, the apparatus including a sensor, a transmitter, a power supply, and a flexible substrate having at least the transmitter and the power supply connected thereto in low profile enabling disposition of the apparatus adjacent a human body;
