SELF-POWERED DEVICE AND METHOD FOR MEASURING A PARAMETER OF A SENSING POWER CELL
WO22129270
A self-powered device and a method for measuring a parameter of a sensing power cell are disclosed. The device comprises an electronic unit to be connected to a sensing power cell; a parameter associated to the sensing power cell being measurable via the electronic unit. The electronic unit includes a storage element to be charged by the sensing power cell via a charging voltage; a sensing module to measure a generated electrical current during the charging of the storage element, and to generate a voltage as a result; a data interface module connected to the sensing module to receive the generated voltage; and a detection module to monitor the charging voltage, and, when the latter has reached a pre-configured polarization voltage, to indicate to the data interface module to convert the received voltage to a readable result. A Point-of-care device is also disclosed.
- Ease of use - Does not require the use of batteries - Low design cost - Low production cost (basically a piece of paper with 3 indicator LEDs, for example) - Can be implemented on any substrate (paper, flexible material, etc.) - Reliable and repeatable, capable of reliably discriminating between Yes and No. The system is useful for cases where quick classifications are needed, with a Yes/No response or a gradation between a maximum and a minimum value (semi-quantitative approach).
