Abstract

The present invention describes physiological sensors embodiment having a pressure ring around the sensors. The pressure ring embodiment is compressible and stretchable and non shearable. One or more electrode sensors embodiments are integrated to a stretchable strap that can be worn by a person on the torso. This system is capable of monitoring and measuring physiological information of the wearer more accurately and reliably and providing a comfortable to wear platform at the same time. Further the sensors in the embodiment can be replaced by actuators and used as an actuator embodiment with lesser motion artifacts.

Claims

1. A sensor embodiment or encapsulating device that can be connected embedded on or in a stretchable material worn by a mammal that comprises of at least one an electrically insulating ring that compresses the skin of the wearer so that the skin inside the ring lifts up and touches with the sensor elements of the embodiment such that.

(a) The sensors are connected or embedded the inside surface of the embodiment encircled by the ring.

2. A device according to claim 1 where the sensors are an bio potential electrodes, pulse oximetry or pulse plethysmography (PPG/SpO₂) sensors, thermal sensors, blood gas sensors or chemical sensors.

3. An embodiment according to claim 1 having actuators instead of the sensors inside surface of the embodiment that touches the skin of the wearer.

5. Use of one or more sensor embodiments in claim 1 or measuring or monitoring at least one physiological signal characteristics or event of the wearer.

6. A device according to claim 1 where the embodiment sensors are electrically connected with a signal or power caring cables

7. The embodiment according to claim 1 made out of materials that are allowed to compress in the direction 006, bendable in the direction 005 and not stretchable or not shearable along the directions 010 and 011.

8. A device according to claim 1 where the construction can be carried out via mechanically chemically or thermally connecting layers or by using a mould.

9. A device according to claim 1 where the materials used in the embodiment are being foam, rubber, plastic, polymeric, ceramic and any combination of any of these.

10. A device according to claim 1 where the sensor is embedded or integrated together with the stretchable material and then the embodiment is put in either by using molding or layer construction methods or combination of both approaches.

11. A device according to claim 1 where the device can be made by using flexible materials such as polymeric materials and a stiffener is used to get the required stiffness and mechanical properties of the embodiment.

12. The sensor surface that touches the skin according to a device in claim 1 having an electro conductive or thermal conductive adhesive layer.

4. The actuators in claim 4 comprise of heaters, electrodes or trans epidermal drug delivery units.
