Touch sensing devices, sensing devices for recognizing a user's gesture, electronic devices, and devices for detecting a physiological signal

A sensing device for recognizing a user's gesture, comprising:

• multiple touch sensing devices, the multiple touch sensing devices being arranged in an array, and the multiple touch sensing devices generating an electrical signal in response to the user's gesture;
• and
• a processor configured to determine a sliding direction of the user's gesture based on position information of at least two of the multiple touch sensing devices and a time when the electrical signal is generated, wherein one of the multiple touch sensing devices includes:
• an air pressure sensor having a hole portion, an interior of the air pressure sensor being in flow communication with an exterior of the air pressure sensor through the hole portion;
• and
• a sealing structure connected to the air pressure sensor, the sealing structure and the air pressure sensor forming a cavity, the cavity being in flow communication with the interior of the air pressure sensor through the hole portion, wherein,
• a part of the cavity enclosed by the sealing structure deforms under user contact, and the deformation causes a change of an air pressure in the cavity, the air pressure sensor receives the change of the air pressure in the cavity through the hole portion and converts the change of the air pressure into the electrical signal;
• and
• the sealing structure includes a connecting portion and a membranous structure, an end of the connecting portion being connected to an end of the air pressure sensor, the other end of the connecting portion being connected to the membranous structure, and the membranous structure, the connecting portion, and the end of the air pressure sensor forming the cavity, wherein a thickness of the membranous structure is in a range of 0.05 mm to 0.3 mm.
