Abstract
An improved crystal oscillator package is described in which the crystal oscillators are attached to ceramic substrates by means of connectors, formed from materials such as silver-platinum and silver, using thick film techniques. An optional opening in the substrate allows a liquid or gaseous medium to make easy contact with the oscillator chips' electrodes on which a biosensitive film of a specific receptor has been deposited, thereby allowing the crystals to act as detectors. In the case of the multi-oscillator module, several different detectors may be present in the same unit.
