Abstract

Przedmiotem zgłoszenia jest moduł wytwarzania energii zawierający przetwornik ciśnienia lub temperatury charakteryzujący się tym, że zawiera hermetyczną komorę (5) zawierającą dno oraz ścianki, przy czym ścianki komory (5) stanowi krzemowa warstwa podłożowa (3), na której umieszczona jest warstwa tlenku zagrzebanego (2), a dno stanowi pokrywka hermetyzująca (4), na której znajduje się płynna warstwa substancji poddanej przemianie fazowej podczas pracy modułu (12), ponadto wnęka jest zamknięta od góry bistabilną membraną (1), podatną na odkształcenie pod wpływem różnicy ciśnień pomiędzy wnętrzem, a zewnętrzem komory (5), na membranie umieszczona jest warstwa piezoelektryczna (7), na której umieszczona jest metalowa elektroda (6), jednocześnie na elektrodzie metalowej (6) umieszczony jest pierwszy kontakt elektryczny (9), a na membranie krzemowej (1) umieszczony jest drugi kontakt elektryczny (10), jednocześnie we wnętrzu komory (5) znajduje się płynna substancja, której część ulega przemianie fazowej ciecz-gaz podczas pracy modułu (11). Przedmiotem zgłoszenia jest również zestaw modułów zgodnie z zastrzeżeniem od 1 do 2, połączonych równolegle lub szeregowo w matrycę modułów. Przedmiotem zgłoszenia jest także zastosowanie zestawu modułu wg wynalazku do zasilania węzłów sieci IoT.The subject of the application is a power generation module containing a pressure or temperature transducer characterized in that it contains a hermetic chamber (5) containing a bottom and walls, wherein the walls of the chamber (5) are a silicon substrate layer (3) on which a buried oxide layer (2) is placed, and the bottom is a hermetic cover (4) on which there is a liquid layer of a substance subjected to a phase change during the operation of the module (12), furthermore the cavity is closed from the top with a bistable membrane (1) susceptible to deformation under the influence of the pressure difference between the interior and the exterior of the chamber (5), a piezoelectric layer (7) is placed on the membrane, on which a metal electrode (6) is placed, at the same time a first electrical contact (9) is placed on the metal electrode (6), and a second electrical contact (10) is placed on the silicon membrane (1), at the same time inside the chamber (5) there is a liquid substance, part of which undergoes a liquid-gas phase change during the operation of the module (11). The subject of the application is also a set of modules according to claim 1 to 2, connected in parallel or in series in a matrix of modules. The subject of the application is also the use of a set of modules according to the invention for powering IoT network nodes.
