Abstract
A biological information pressure sensor having a planer shape disposed on an elastic support element for supporting a human body, for detecting an external force due to one or both of a load variation caused by the human body and vibration generated by the human body. The sensor includes a sensing portion having sensitivity with respect to the external force, wherein the sensing portion is configured by using a piezoelectric material, and is configured to have flexibility and anisotropy.
Claims19
A biological information pressure sensor having a planer shape disposed on an elastic support element that supports a human body, wherein the sensor detects an external force due to one or both of a load variation caused by the human body and vibration generated by the human body, the sensor comprising:
- a sensing portion that detects the vibration generated by the human body, wherein the sensing portion includes a piezoelectric material that includes a plurality of different thicknesses so as to be more flexible in a predetermined direction of the sensing portion than in other directions of the sensing portion.
A biological information pressure sensor having a planer shape disposed on an elastic support element that supports a human body, wherein the sensor detects an external force due to one or both of a load variation caused by the human body and vibration generated by the human body, the sensor comprising:
- a sensing portion having sensitivity with respect to the external force, wherein the sensing portion includes a piezoelectric material, and is configured to have flexibility and anisotropy,
- wherein a groove is provided on an outer surface of the sensing portion so that the thickness of the piezoelectric material is partially varied.
A biological information pressure sensor having a planer shape disposed on an elastic support element that supports a human body, wherein the sensor detects an external force due to one or both of a load variation caused by the human body and vibration generated by the human body, the sensor comprising:
- a sensing portion that detects the vibration generated by the human body, wherein the sensing portion includes a sensor portion formed by a piezoelectric material and a base portion that holds the sensor portion, the base portion including a plurality of different thicknesses so as to be more flexible in a predetermined direction of the sensing portion than in other directions of the sensing portion.
