Pyro/piezo sensor and stimulator hybrid circuit

A system for treating a patient with a sleep disorder, the system comprising:

• a pyro/piezoelectric film sensor and stimulator configured to detect respiration information of the patient and to provide stimulation to the patient;
• a closed loop neuromodulator configured to provide a control signal to a hybrid circuit, to receive the respiration information from the hybrid circuit, and to provide the stimulation energy to the hybrid circuit, the hybrid circuit including:
• a control input configured to receive the control signal from a closed loop neuromodulator, the control signal having a first state and a second state;
• a sense switch configured to provide the respiration information from the pyro/piezoelectric film sensor and stimulator to the closed loop neuromodulator in response to the first state of the received control signal;
• and
• a stimulation switch configured to provide the stimulation energy from the closed loop neuromodulator to the pyro/piezoelectric film sensor and stimulator in response to the second state of the received control signal;
• wherein the hybrid circuit is configured to couple to the pyro/piezoelectric film sensor and stimulator using a single wire pair;
• and
• wherein the stimulation is provided to the patient using the stimulation energy.

A method comprising:

• receiving a control signal at a hybrid circuit, the control signal having a first state and a second state;
• providing respiration information from a pyro/piezoelectric film sensor and stimulator to a closed loop neuromodulator in response to the first state of the control signal;
• providing stimulation energy from the closed loop neuromodulator to the pyro/piezoelectric film sensor and stimulator in response to the second state of the control signal;
• and
• wherein the providing the respiration information and the providing the stimulation energy includes using a single wire pair coupling the pyro/piezoelectric film sensor and stimulator to the hybrid circuit.
