ST introduction of 'Smart' contact lenses embedded wireless sensor – 808nm Diode Laser K81D15F-5.00W
STMicroelectronics has announced the design for the Swiss SensimedAG company developed a breakthrough platform for wireless MEMS sensors, this unique sensor embedded in contact lenses can be used as the platform for additional data read-out transducer electronic systems, antennas and mechanical support components. Through early diagnosis and tailored for the individual the best treatment, the solution to more effectively take care of glaucoma patients.
The name SENSIMEDTriggerfish ® solution, based on a "smart" contact lens, using an embedded micro strain gauge continuous period of time (usually 24 hours) to monitor the curvature of the eye, can present a common eye doctors device can not obtain important data on disease management.
Glaucoma is the world's second largest blinding eye diseases, is a progressive and irreversible eye by the disease, eventually leading to blind patients with eyes. Although glaucoma can not be cured, but if diagnosed in time and get proper treatment, you can still control the progression of the disease. Standard test is regular eye doctor-patient testing using tonometer intraocular pressure (IOP). However, the intraocular pressure may not be able to detect elevated intraocular pressure, especially in glaucoma patients, IOP in the day because of volatility, usually sleeping or out of time outside the peak, only when the eyes are often under great damage by only after the diagnosis of disease. Did not receive timely treatment because many of the deteriorating condition of glaucoma patients.
Sensimed innovative solution consists of two components: smart contact lenses in patients with neck and wearing a small receiver. In addition to strain gages, the contact lenses is also embedded antennas, micro-processing circuit, and dedicated to send measurement data to the receiver RF transmitter. Contact lens power from the received radio waves, so no need to connect the battery. Embedded component in the lens on the layout of the ingenious, does not interfere with the vision of patients. Contact lenses fitted by the ophthalmologists to patients, when patients return visit the next day, remove the glasses and the receiver an ophthalmologist, you can read in the last 24 hours, the IOP changes in the complete record of data.
Sensimed CEO Jean-MarcWismer said: "The trial proved that our unique platform to bring great benefits for the glaucoma treatment, the next step in the selected areas to more medical centers to promote this product. STMicroelectronics MEMS sensors in high-precision development aspects of the performance was outstanding, they already have partners with an innovative full capacity, the natural choice is the key stage partner. "
SENSIMEDTriggerfish ® CE mark has been made in 4 large-scale trials currently under way, and in designated medical centers have products available for commercial sale. "The equipment is simple to use, can greatly simplify and improve the way patient care." Trial in the University Hospital of Geneva, Switzerland, said Dr. Triggerfish's KawehMansouri.
STMicroelectronics engineers working with Sensimed together to make this breakthrough technology into a reliable mass-produced MEMS products. STMicroelectronics expects to complete the second quarter of 2010, the development of MEMS sensor design, the 2010 third quarter production. To go through the approval of the relevant laws and regulations in order to center to try other than doctors and patients to promote. Sensimed and STMicroelectronics are expected from the third quarter of 2010, launched in European countries, and in the end of 2011 to enter the U.S. market.
STMicroelectronics MEMS, sensors and high-performance analog products BenedettoVigna general manager, said: "STMicroelectronics particular focus on diagnostic and other medical equipment for the development of wireless sensor networks, this body wear self-powered wireless sensor for innovative products , is expected to treat millions of potential and existing groups of glaucoma patients. Sensimed innovative application of force to prove STMicroelectronics perfectly how cooperation with healthcare professionals, integration of two completely different disciplines and skills, use of our manufacturing infrastructure and improve people's health and well-being.
