Wireless MEMS Sensor for Glaucoma Diagnosis
STMicroelectronics (Geneva, Switzerland) has developed a wireless MEMS sensor that acts as a transducer, antenna, and mechanical support for the SENSIMED Triggerfish® continuous eye pressure monitor from Sensimed AG. The solution will enable better management of glaucoma patients via earlier diagnosis and treatment that is tailored to each patient.

The solution is based on a “smart” contact lens that uses a tiny embedded strain gauge to monitor the curvature of the eye over a period of 24 hours, providing disease management data that is not obtainable using conventional ophthalmic equipment.

The lens also contains an antenna, a tiny dedicated processing circuit, and an RF transmitter that communicate the measurements to a receiver worn around the patient's neck. Because it is powered via the received radio waves, it does not need to be connected to a battery.

Logarithmic Sensor
New Imaging Technologies (Evry, France) has introduced the MD1- 10-B logarithmic sensor, which uses an array of photodiodes operated in photovoltaic mode.

In most logarithmic imager designs, linear photo current passes through a MOS transistor whose exponential characteristic transforms photo current into a logarithmic-like voltage output signal.

In NIT’s MAGIC approach, the array of photodiodes is operated in photovoltaic mode and the open-circuit voltage across the p/n junction is proportional to the exact and pure logarithmic value of the incident light intensity.

When equipped with the sensor, the MCD1-10-BW analog camera modules provide dynamic range performance greater than 120 dB.
