High-frequency Transmitter and Associated Operating Method

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a high-frequency transmitter that is fully energy-autonomous, using an energy converter (such as a solar cell, piezoelectric, or thermoelectric element) not only to power the transmitter but also to receive non-electrical control signals (like light, vibration, or temperature changes) for device activation and configuration. This enables ultra-low power, long-life wireless sensor nodes that can be controlled or awakened by specific environmental impulses, rather than requiring conventional electrical inputs or constant external power sources.

Use CasesContent extracted from patent full text and abstract with AI.

• Wireless sensor networks for environmental monitoring (e.g., temperature, vibration) in industrial or remote locations.
• Tire pressure or condition monitoring systems that use vibrations for energy and activation.
• Structural health monitoring for buildings, bridges, or rotating machinery, where sensors can be activated or configured wirelessly.
• Asset tracking and inventory control systems with ultra-small, maintenance-free transponders.
• Medical implants or wearables that operate autonomously and respond to external non-electrical stimuli.

BenefitsContent extracted from patent full text and abstract with AI.

• Completely wireless and energy-autonomous operation, reducing or eliminating maintenance (e.g., battery changes).
• Capability for very small device size (less than 1 cm³), enabling new applications where space is limited.
• Long operational lifetime due to extremely low power consumption and energy harvesting.
• Non-electrical control (via light flashes, vibrations, temperature changes) enables secure, interference-resistant activation and configuration—even in electrically noisy or inaccessible environments.
• Highly configurable, allowing for easy adaptation to different applications or requirements without physical reprogramming or wiring.

Patent Abstract

The invention relates to a high-frequency transmitter and an associated operating method. Said high-frequency transmitter (1) contains: an energy transducer (2) for supplying energy to the high-frequency transmitter; a logic component (3) that is connected to a receiver circuit for the executive sequencing of the high-frequency transmitter; and a high-frequency transmission stage for radio communication. According to the invention, at least some regions of the energy transducer (2) are designed as an input element for non-electric control signals, in order to generate electric input signals for the receiver circuit.
