Abstract: A universal electrochemical micro-sensor can be used either as a biosensor or an environmental sensor. Because of its small size and flexibility, the micro-sensor is suitable for continuous use to monitor fluids within a live subject, or as an environmental monitor. The micro-sensor can be formed on a reusable glass carrier substrate. A flexible polymer backing, together with a set of electrodes, forms a reservoir that contains an electrolytic fluid chemical reagent. During fabrication, the glass carrier substrate protects the fluid chemical reagent from degradation. A conductive micromesh further contains the reagent while allowing partial exposure to the ambient biological or atmospheric environment. The micromesh density can be altered to accommodate fluid reagents having different viscosities. Flexibility is achieved by attaching a thick polymer tape and peeling away the micro-sensor from the glass carrier substrate. The final structure is thereby transferred to the polymer tape, providing a flexible product.

Abstract: A bio-fluid sensor is formed by depositing polyimide on a glass substrate. Gold and platinum are deposited on the polyimide and patterned to form fluid sensing electrodes, signal traces, and a temperature sensor. The fluid sensor is then fixed to a flexible tape and peeled off of the glass substrate.

Abstract: A bio-fluid test strip includes a fluid receiving area and a contact pad area for interfacing with a fluid sensing device. The test strip includes a fluid sensing electrodes and a first temperature sensing resistor in the fluid receiving area. The test strip further includes a second temperature sensing resistor in the contact pad area. The first and second temperature sensing resistors together provide an indication of the temperature difference between the fluid sensing area and ambience.
