Abstract: Sensor packages and manufacturing methods thereof are disclosed. One of the sensor packages includes a semiconductor chip and a redistribution layer structure. The semiconductor chip has a sensing surface. The redistribution layer structure is arranged to form an antenna transmitter structure aside the semiconductor chip and an antenna receiver structure over the sensing surface of the semiconductor chip.

Abstract: A display system includes a display device and an HDMI dongle electrically connected to the display device. The display device includes a first transmission interface, a first control module, and a power supply module. The HDMI dongle includes a second transmission interface and a second control module. The first and the second transmission interfaces include transmission pins corresponding to each other. The first control module detects voltage of one pin to obtain matching state between the display device and the HDMI dongle and outputs an enabling signal. When the HDMI dongle matches the display device, the enabling signal controls the power supply module to transmit the power supply signal to the second control module through the first and the second transmission interfaces for charging the second control module. When the HDMI dongle does not match the display device, the power supply module is not transmitted to the second control module.

Abstract: An economic, direct synthetic method for producing water soluble QDs that are ready for bioconjugation is provided. The method can produce aqueous QDs with emission wavelengths varying from 400 nm to 700 nm. Highly luminescent metal sulfide (MS) QDs are produced via an aqueous synthesis route. MS QDs are capped with thiol-containing charged molecules in a single step. The resultant MS QDs exhibit the distinctive excitonic photoluminescence desired of QDs and can be fabricated to avoid undesirable broadband emissions at higher wavelengths. This provides a significant improvement over the present complex and expensive commercial processes for the production of QDs. The aqueous QDs are stable in biological fluids over a long period of time. In addition, nontoxic ZnS QDs have been produced with good photoluminescence properties by refluxing the ZnS QD suspensions over a period of time.

Abstract: A piezoelectric cantilever with a non-piezoelectric, or piezoelectric tip useful as mass and viscosity sensors. The change in the cantilever mass can be accurately quantified by monitoring a resonance frequency shift of the cantilever. For bio-detection, antibodies or other specific receptors of target antigens may be immobilized on the cantilever surface, preferably on the non-piezoelectric tip. For chemical detection, high surface-area selective absorbent materials are coated on the cantilever tip. Binding of the target antigens or analytes to the cantilever surface increases the cantilever mass. Detection of target antigens or analytes is achieved by monitoring the cantilever's resonance frequency and determining the resonance frequency shift that is due to the mass of the adsorbed target antigens on the cantilever surface. The use of a piezoelectric unimorph cantilever allows both electrical actuation and electrical sensing.

Abstract: A method to produce low-temperature sinterable powders which are then subsequently used to fabricate freestanding piezoelectric films with very large electric-field-enhanced piezoelectric response is provided. The ?d31 coefficient for PMN-PT layers can be as high as 2000 pm/V, larger than that of commercial single crystalline PMN-PT bulk materials, at 10 kV/cm (or 20 V over the 20-micron film thickness). In contrast to single crystals, the polycrystalline freestanding films are easy to fabricate and can be made into any size. The films are also easily miniaturized. The method can be applied to nearly any piezoelectric material.

Abstract: A PEFS (Piezoelectric Finger Sensor) acts as an “electronic finger” capable of accurately and non-destructively measuring both the Young's compression modulus and shear modulus of tissues with gentle touches to the surface. The PEFS measures both the Young's compression modulus and shear modulus variations in tissue generating a less than one-millimeter spatial resolution up to a depth of several centimeters. This offers great potential for in-vivo early detection of diseases. A portable hand-held device is also disclosed. The PEF offers superior sensitivity.
