MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202511114901 A) filed by UPES, Dehradun, Uttarakhand, on Nov. 21, 2025, for 'a system and method for passive doorframe intrusion detection using embedded piezoelectric energy harvesting and multi-modal alerts.'
Inventor(s) include Akashdeep Bhardwaj.
The application for the patent was published on Jan. 9, under issue no. 02/2026.
According to the abstract released by the Intellectual Property India: "A passive doorframe intrusion detection system is disclosed for the technical field of security monitoring, integrating a sensor assembly (10) with ultra-thin mechanical pressure plates (10A) embedded within a doorframe to capture mechanical deformations. The system utilizes a piezoelectric energy harvesting unit (20) to convert these deformations into electrical signals, which are stored in a capacitor-based power buffer (30) and monitored by a voltage-threshold based trigger circuit (40). Upon surpassing a predefined energy threshold, a multi-modal alert system (50, 60, 70), including a mechanically actuated spring-driven siren (50), a wireless communication module (60), and a microfluidic tamper seal (70) is activated. An electromagnetic sensing module (80) further detects magnetic variations, and all components are protected within a tamper-resistant enclosure (90)."
