Our goal is to make RFID tags and sensors very economically, so they can be used in high volume for many mobile assets, from tyres to filters and beyond. We are constantly designing inlays, patches and labels on a wide range of substrates that are thin, light, transparent, rigid and flexible, and that transmit in both UHF and NFC.
Right now we are working with printable technology on materials compatible with tyres and their hot- curing manufacturing process (up to 200psi and 185°C). Additive printing avoids expensive vacuum and high temperature processing, so we are very confident of achieving our goal, which will be a double winner when self-powered by Energy Harvesting.
We are deeply engaged in R&D for Energy Harvesting as this is key to being able to make and supply self-powered strips of tags and sensors that can go ‘behind the dashboard’. Right now our focus is on tyres for heavy vehicles. In this we are supported by major tyre manufacturers.
Several concurrent projects are independently using piezoelectric and kinetic properties of different materials to generate power and provide data about a tyre’s properties to determine what is the best construct, given each specific tyre’s composition and manufacturing process, as these can vary.

Silent Sensors is broadening exploitation opportunities from tyres to rubber, polymers and elastomers in general. Thanks to our collaboration with Avon Rubber and Bridgestone, we have identified a universal substrate that has the mechanical properties necessary for embedding RFID and 2D tags into rubber during curing at high temperature and pressure.
This property is also required for the dairy liners and protective equipment made by Avon Rubber. These are produced using injection moulding techniques with high temperature and pressure in much the same way tyres are made.
Thanks to our research in roll-to-roll manufacturing, Silent Sensors has formulated ‘inks’ that can be printed onto special substrates. This lets us mass-produce RFID tags at a lower price point than traditional techniques. This process also lets us produce the energy harvesting and energy storage materials we are developing with the University of Bath and CPI.
Radio transmission frequencies are set by international agencies. Our solutions conventionally work in UHF at 2.4GHz and 433MHz, BLE and NFC. Our hubs and routers work in licensed telecom channels. Our R&D is focused on designing and incorporating transmission devices and antennas into printable substrates, including ones that can harvest energy.
Very often this is custom R&D for Solution Engineering projects.
The Giants of Computing – Google, Amazon, Microsoft, IBM and others – do R&D for Cloud based computing. We are researching distributed ledger and blockchain technology as decentralised but secure alternatives to traditional databases.
We develop data structures, logic, rules, timeliness, delivery and transformation of data into actionable information that users need, based on the specific application they are using. We also design browser-based dashboards and smartphone based apps for monitoring the status and managing the performance of connected assets.
Companies who don’t need our skills in database and app design or development can use the open APIs that come with all our solutions.
