[Development Product] Battery-less Multi-purpose Sensor

We are developing a battery-less multi-purpose sensor that applies the power generation principle of liquid detection sensors to detect various external forces and physical changes!

We introduce a battery-less multi-purpose sensor using Mg air batteries. ■ Battery-less Sensor This is a groundbreaking device that applies and further evolves the technology of battery-less liquid detection sensors. The core of this sensor consists of a sensor element that starts generating power when it comes into contact with water, a water bag, and a wireless transmitter (BLE or LPWA) integrated into one structure. When an external force is applied, the internal water bag bursts, generating power and activating the wireless transmitter. The most significant feature is its battery-less design, which allows installation in locations where power supply is difficult and can withstand long periods of inactivity, greatly contributing to labor reduction. ■ Design Versatility This unique design allows it to function as a sensor that responds to various external forces such as pressure, tensile force, shear force, and impact force. By customizing the case design, it can accommodate a wide range of applications. ■ Expected Applications The expected applications are diverse: 1. Drone drop detection sensor 2. Snow accumulation detection sensor for snowy mountains 3. Crack propagation detection sensor for bridge components It has the flexibility to be utilized in various fields and situations, depending on the customer's ideas.
