Embedded Wireless Sensing
Inductosense is developing innovative compact, wireless sensors for fast, repeatable detection of cracks, corrosion or defects in structures or products.
The Wireless and Non-Destructive (WAND) system consists of a thin embeddable ultrasonic sensor and a handheld measurement probe. The probe wirelessly couples to the sensor to provide the power and take the measurement. The sensor does not contain wires or a battery and can therefore be permanently attached to, or embedded into, a structure.
The WAND Evaluation System is ideally suited to making thickness measurements across structures. It consists of a pack of 20 sensors (either 2MHz or 5MHz), a hand-held measurement probe and a sensor fixing kit. The ultrasonic A-scan is displayed on the probe’s screen along with the calculated thickness and the data can also be viewed and analysed using the web-based software.

WAND Evaluation System
The WAND sensors can be cost-effectively deployed across structures at locations where conventional Non-Destructive Testing (NDT) is undertaken. Permanent sensing enables repeatable measurements and trending of data over time. Once the sensors are attached the measurement can be taken quickly without accurate alignment saving inspection time and costs.
The WAND sensors can be embedded underneath a coating or insulation layer. An NDT measurement of the underlying structure can then be taken without removing the layer. This saves the cost, time and down-time of preparing a structure for an inspection.
The WAND sensors can be permanently fixed into a structure (such as a wind turbine blade). An inspection on internal components of the structure can then be made by bringing the handheld probe close to the outside. This can facilitate NDT during manufacture and enables through life inspection.
Composite wraps are often used for internal and external corrosion on pipes and other structures. Once the repair is applied it is usually not possible to monitor the underlying structure using ultrasonic methods. The WAND sensor can be embedded underneath a composite wrap enabling the inspection to be performed on the repaired area.
Performing NDT measurements on large structures or difficult to reach structures can require significant skilled manpower, equipment and time. Once the WAND sensor is fixed to a structure, the measurement can be made remotely with the WAND probe electronics fitted to a unmanned vehicle (such as a crawler or drone).
The passive WAND sensors are thin and lightweight and can be permanently embedded into a product during it’s manufacture. This enables through-life NDT of the product from exactly the same location each time.
