The simple motivation to soften conventional electronic devices is that we as human beings are in soft, biological formats, and wish to turn electronics into similar manner as our bodies. Not only for enhanced user experience, but also for enabling a broad spectrum of new applications. Reversible deformability, transparency, and lightweight are desired features for future electronics. Devices based on this new technology will be fold-able, twistable, and stretchable into almost arbitrary curvilinear shapes. Application examples may range from ultrathin, conformable health monitoring tapes that seamlessly attach to the skin, electronic/second skin, to elastomeric medical implants that are truly biocompatible to the tissues. 

Methods and iastmments that are used to monitor phosgene content ia air are well developed and have been reviewed (46—48). One detection iastmment is a porous tape that measures the concentration of phosgene ia air ia quantities as small as 6 ppb (49). Fourier transform ir spectrometry techniques have been developed to permit line and area monitoring ia the area around phosgene plants (50). 

For many reasons, it may be ineonvenient to take the speetrum analyzer to the field eaeh time an analysis is to be made. Often, several maehines are to be analyzed at various loeations. Also, a hostile environment may exist at the test site, whieh might result in damage to the analyzer. A way of over-eoming these problems is offered by data taping. With a tape, a permanent reeord is made. Sinee eaeh ehannel of the tape offers a plaee for data to be stored, this reeord may be a eondensation of several inputs either from different transdueers or from the same transdueer at various loeations. A eontinuous tape monitor is very benefieial. In the event of maehine failure, an analysis of the playbaek will help diagnose the problem. 

Flange taping Apply masking tape to all pipe and vessel flanges. Same as in Step 1. Seal space between flanges and punch 1.5mm hole in tape for monitoring leaks. 

Pressure sensitive labels and tapes for the consumer markets form a very significant portion of the PSA industry. Whereas the original products were rather simple in construction and use, today s products often perform unique functions that result from more sophisticated assembly of a label or tape product. Examples of these unique functions include the monitoring of food or drug storage conditions, or the ability to monitor the charge status of a battery. 

It is advisable to identify all your quality records within your procedures. This will avoid arguments on what is or is not a quality record, because once you have chosen to identify a record as a quality record you have invoked all the requirements that are addressed in this chapter. Any document which describes the achieved features and characteristics of a product or service are quality records. Those records which will demonstrate that work has been planned, organized, resourced, monitored, verified, and corrected when found deficient are also quality records. The note following the requirement acknowledges that quality records can be in hard copy or held on a computer disk or magnetic tape. Should both forms be held, you will need to declare which are the masters and provide the appropriate security to prevent inadvertent loss or damage (see below). 

The monitoring of temperatures for electronic control systems is now mainly by thermocouples, secured onto the outside of the pipe with self-adhesive tape and the pipe then insulated over.

A couple of conventional methods are available to measure the apparent LNAPL product thickness in a monitoring well. The apparent thickness of LNAPL product in a well is typically determined using either a steel tape with water-and-oil-finding... 

The sensor head is lowered into a monitoring well. Upon contact with any fluid, the float ball is raised and a continuous tone emitted from an audible alarm. When the sensor head contacts the interface between LNAPL and groundwater, the change in conductive properties is detected by the electrical conductivity sensor and a beeping tone is emitted. The distances along the tape at which the two changes in the audible alarm occur are recorded as referenced from a presurveyed point on the lip of the monitoring well. The resultant distance is equivalent to the apparent thickness of the LNAPL in the well.
