A sensor and method for measuring the concentration of one or more chemical substances within a solution. The sensor including a body of saturated hydrogel held within a sensor body
(KD Scientific, C/N 78-9410). These were connected with a custom-made chamber apparatus created following design criteria elaborated by Mooney et al22. and of inner diameter of 31 mm. The chamber delimited a fillable volume of 15 mL and was connected to a pressure sensor (Honeywell, ...
2c). To measure the force generated by the unit-segment hydrogel actuator, the actuator was placed between a rigid bottom plate and an acrylic fixture connected to a force sensor (NeuLog; Fisher Scientific) (Supplementary Fig. 5a). Then, water was slowly infused into the actuator with the ...
Furthermore, a flexible sensor based on the hydrogel was fabricated, which exhibited a sensitivity of 0.41, a detection range of 1鈥 400%, and a response time of 300ms, respectively, capable of being used for human motion detection. Overall, this work provided a new idea for the integrated...
The terms “sensory receptors”, “target specialized cells”, “sensor cells”, and “first cells”, which may be used interchangeably herein, are used to denote a group of probing or sensing elements configured to produce an optical output (as a non-limiting example—fluorescence, luminescence...
CB hydrogels have been gaining popularity in fabrication of smart devices because of their overall biocompatibility, high storage capacity for cells and small molecules and low interfacial tension at the gel-aqueous solution interface (Tokarev and Minko 2009). Smart device like biochemical sensor transla...
The multifunctional ionic hydrogel can beused as soft conductors for application in flexible devices such asionic skin for wearable sensors and luminescence display. 展开 关键词: multiple sensibility hydrogel sensor flexibility stretchable electric lithium ionic conductor ...
The data acquisition system logged the given load from a load-displacement sensor (Linearly Variable Differential Transducer, LVDT; 1 kN load cell). LVDT recorded the crosshead position of the actuator with respect to time and a fixed frequency. 2.6.8. Swelling and deswelling experiments ...
strain, and previous studies have reported that proper mechanical tension promotes intercellular E-cadherin formation47,48. We stretched HaCaT cells at 5% strain for 4 h. The results showed that clear and intact intercellular E-cadherin was formed in the HC and HCF groups. Therefore, we used...
long-term sealing. Electro-Ox hydrogel tape can also be used to adhere devices onto tissue surfaces to monitor dynamic motion. As an example, we adhered a capacitive strain sensor on a porcine heart via Electro-Ox hydrogel tape (Fig.4e). The heart was cyclically pressurized by intermittent ...
