    • The invention is a bubble-shaped pressure sensing device. This device comprises a flexible integral shell (1), electronic elements (2), a rigid plate (5), battery (6), charging units (3) and sensors (4). The application of this affordable device is for determining the amount of contact pressure. Hence, it can be used in a wide range of industries such as manufacturing medical equipment needing to measure pressure, manufacturing home appliance especially in connection with BMS (Building Management System) and smart homes, vehicle industry, manufacturing furniture such as chairs, sofa, and beds, and any other fields have any need to pressure measuring especially the contact pressure. It has high accuracy in measuring the average pressure exerted to its surface in contact with both rigid and pliable surfaces, as it is capable to be placed under any kind of material with any kind of characteristics. In order to maintain its effectiveness, the material used in producing this invention is scratch-resistant and of high quality. Therefore, the reliability and accessibility of this bubble-shaped technology have been estimated to be desirably high during its long life cycle. Higher reliability leads to a much durable device. The invention has many novel capabilities such as reserving its battery charge for a long time meaning charging action wouldn't be necessary very often, sending the data collected by the sensors (4) to any connected device or cloud wirelessly, and being used collectively with no limit. The last one means that any number of these sensors (4) kits can be used together as a network. This number customization enables the user to optimize the device for their desirable goal according to their need, working load, amount of accuracy and precision, and the required configuration. Interestingly enough, these sensor (4) cells can be connected to each other and to any other sensors including ultrasound and infrared sensors in series or parallel configuration. This configuration depends on the application. If other sensors or devices need to be corrected or validated by using ours, they need to be connected in parallel form. Otherwise, if they need to be working along with each other, the series configuration is recommended.

    • The disclosure provides a force gauge (100), comprising: a housing (130), comprising a first plate element (131) and a second plate element (132). The force gauge (100) further comprises a foil-based sensor element (110), adapted to output an electric signal in response to a force exerted on the sensor element in a thickness direction (T) and/or in a direction of force application (F) of the sensor element (110), at least one spring element (120), arranged to provide a counter force in the thickness direction (T) and/or the direction of force application (F) of the sensor element (110) and having a defined spring characteristic, and at least one abut element (150), adapted to limit a maximum compression of the sensor element (110) in the thickness direction (T) and/or direction of force application (F) of the sensor element (110). The sensor element (110), the spring element (120) and the abut element (150) are sandwiched between inner sides of the first plate element (131) and the second plate element (132). Further, at least the sensor element (110), the spring element (120) and the abut element (150) together at least partly define a signal characteristic of the force gauge (100) within an operational range with a lower limit (L2) and an upper limit (LI).
