摘要: A sensor assembly has a substrate with a microchannel formed therein through which a fluid can flow. At least one sensor is proximate to the microchannel. The temperature of the at least one sensor or fluid may indicate the condition of the fluid, for example, the flow rate and the presence of gas bubbles and particulate substances.

摘要: A small, inexpensive, high quality electret formed by micro-machining technology on a support surface, and further including a small, inexpensive, high quality, self-powered electret sound transducer, preferably in the form of a microphone, formed by micro-machining technology. Each microphone is manufactured as a two-piece unit, comprising a microphone membrane unit and a microphone back plate, at least one of which includes an electret formed by micro-machining technology. When juxtaposed, the two units form a highly reliable, inexpensive microphone that can produce a signal without the need for external biasing, thereby reducing system volume and complexity. In the preferred embodiment, the electret material used is a thin film of spin-on polytetrafluoroethylene (PTFE). An electron gun preferably is used for charge implantation. The electret has a saturated charged density in the range of about 2×105 C/m2 to about 8×10−4 C/m2. Thermal annealing is used to stabilize the implanted charge. Two prototype micro-machined electret microphones have been fabricated and tested. An open circuit sensitivity of about 0.5 mV/Pa has been achieved for a hybrid microphone package.

摘要: A flexible skin formed of silicon islands encapsulated in a polyimide film. The silicon islands preferably include a MEMS device and are connected together by a polyimide film (preferably about 1-100 .mu.m thick). To create the silicon islands, silicon wafers are etched to a desirable thickness (preferably about 10-500 .mu.m) by Si wet etching and then patterned from the back side by reactive ion etching (RIE).

摘要: Microscale valves for use in, e.g., micropump devices, may be formed of a slitted diaphragm bonded o the interior of a valve tube. A bump in the diaphragm and/or a backward-leakage stopper may increase the breakdown pressure of the valve. A push-rod may be used to pre-load the valve membrane to thereby increase the cracking pressure.

摘要: An accommodating intraocular lens has a central chamber with an optical axis extending through a vision-correcting optical zone and a peripheral region at least partially surrounding the optical zone but not interfering with light passing therethrough. At least one peripheral chamber surrounds the central chamber at least partially and functions as a storage reservoir for optical fluid, receiving excess fluid when the central chamber is compressed. Within each peripheral chamber (if there is more than one), a shape-retention member resists collapse of the peripheral chamber in response to external force.
