The invention generally provides molecular biosensors. Such anchor pad may be provided in any one of a multiplicity of different pad shapes, and are adapted to satisfy the required mechanical anchoring and thermal dissipation thresholds for the package, while still enabling high density circuit routing on the printed circuit board under the package. 1:1 measured at a temperature in a range of between about 20 C. In this way, another individual may signal that individual’s intent to perform the shared task and the process may be repeated until the shared task is completed. The PCM is contained in flexible packages.
