Apparatus and method for optical tissue detection

A system operable to optically detect tissue, the system comprising:

• a tissue detection device comprising:
• at least one light source operable to emit light of at least three wavelengths into a material, at least one of the at least three wavelengths being about 980 nanometers;
• and
• at least one photodetector operable to detect at least a portion of the light reflected from the material;
• and
• an electronic device coupled to the tissue detection device and operable to transmit signals to activate the at least one light source and receive data from the at least one photodetector, the electronic device comprising:
• a non-transitory medium coupled with a processor and storing instructions for determining whether the material is a biological tissue of a subject or a non-tissue material and for launching an activity when the material is the biological tissue;
• and
• the processor coupled with the at least one light source and the at least one photodetector, the processor operable to execute the instructions, stored in the non-transitory medium, for:
• determining whether the material is the biological tissue or the non-tissue material based on the light detected by the at least one photodetector,
• when the material is the biological tissue, launching the activity, wherein the activity includes the at least one photodetector recording measurements, and the non-transitory medium is operable to store the recorded measurements, and
• when the material is the non-tissue material, not launching the activity, and initiating an alert by an output device to check placement of the apparatus,
• wherein the at least one light source emits light at predetermined intervals to determine if the at least one photodetector is proximate to the tissue, and
• wherein the at least one light source and the at least one photodetector are operable to be enabled by further activation, wherein the further activation includes the processor detecting a movement.
