Conformable wearable device with deformable shape

A conformable wearable device, comprising:

• a sensor module comprising one or more light emitting components and one or more photodetectors configured to acquire photoplethysmography (PPG) data from a user;
• a deformable material coupled with the sensor module and configured to transition between a planar orientation in an unworn state and a non-planar orientation in a worn state, wherein at least a portion of the sensor module is configured to deform based at least in part on a transition of the deformable material from the planar orientation to the non-planar orientation;
• and
• a flexible material that encases the sensor module and the deformable material, wherein the deformable material is configured to at least partially conform to a body part of the user to enable the one or more light emitting components and the one or more photodetectors to acquire the PPG data when the deformable material is in the worn state, and wherein the deformable material is further configured to retain the non-planar orientation after being conformed to the body part of the user.
