Conventional MEMS based sensors operate at much lower frequencies and have low Q-factors. This means that electronic reader operates in inductive coupling instead of radiation mode. These sensors need bulky pick up loops and interrogation requires high power reader; bulky and not wearable.
After over 12 years research and development at Imperial College London, the team has developed a portable wireless sensing platform technology suitable for medical application, consisting of an implantable miniature sensor, a battery-powered portable electronic reader and a small and flexible external patch antenna.
Reco Medical's sensor technology based on Surface Acoustic Wave (SAW) resonators with high Q-factor operating in the licence-free band in Europe, USA, China and most countries. Compared to conventional low Q-factor MEMS sensors using inductive coupling, high Q-factor and high operating frequency of the SAW resonators allow for smaller sensor dimensions and much lower power consumption - a miniaturised implant and a portable reader providing continuous wireless sensing. Although there are wireless monitoring systems in the medical market, none of them offer wearability that is achievable due to the unique combination of technologies used in our system.
