Abstract
(EN)
An example liquid level sensor is described. The liquid level sensor includes a first layer, a stretchable electrode layer provided on the first layer, and a second layer provided on the stretchable electrode layer. The stretchable electrode layer includes a first stretchable receiver electrode and a stretchable transmitter electrode. The liquid level sensor can include an electrical connector for coupling the liquid level sensor to a computing device. The computing device can be configured to determine a liquid level within the container and wirelessly transmit data indicative of the liquid level.

La présente invention concerne un capteur de niveau de liquide donné à titre d'exemple. Le capteur de niveau de liquide comprend une première couche, une couche d'électrodes extensible disposée sur la première couche et une seconde couche disposée sur la couche d'électrodes extensible. La couche d'électrodes extensible comprend une première électrode de récepteur extensible et une électrode d'émetteur extensible. Le capteur de niveau de liquide peut comprendre un connecteur électrique pour coupler le capteur de niveau de liquide à un dispositif informatique. Le dispositif informatique peut être conçu pour déterminer un niveau de liquide à l'intérieur du récipient et transmettre sans fil des données indiquant le niveau de liquide.
