Smartrac’s state-of-the-art Sensor Patch broadens the company’s inlay and tag product range for passive sensor inlays. It is specially designed to measure moisture conditions in medical care areas, e.g. geriatric care, long-term medical care and childcare.

The Smartrac Sensor Patch is a passive UHF inlay equipped with Axzon Magnus®S2 IC. This RFID sensor inlay offers great performance, and accurately detects urine levels in the diaper. The specific antenna design acts as a resistor/inductor/capacitor (RLC) tuned circuit to enable an antenna to sense its environment. The antenna converts environmental data into an impedance change, and then the sensor tag IC translates this into a sensor code, as it dynamically matches antenna impedance to die impedance. The sensing information is digitized and wirelessly communicated to off-the-shelf readers using a standard UHF Gen 2 protocol READ command for further processing by caregivers.

The innovative Sensor Patch is a disposable, UHF, single-chip sensor inlay solution that offers cost efficiency, is easy to implement, and works on different textiles, pulps and nonwoven materials. The inlay is attached outside of the diaper to avoid skin irritation. In industrial diaper production, the inlay can be placed between the diaper’s layers to remain invisible to end users. It is deployable where active or semi-active sensors are not practical, and involves no battery maintenance, costs or problems with product lifetime or recycling.

Delivery formats are dry and wet to suit all converting-industry needs, and the inlay complies with all relevant industry standards and strict quality control parameters.
