Embodiments of the present disclosure provide techniques and configurations for a wearable sensor apparatus. In one instance, the apparatus may comprise a flexible substrate and conductive fabric component that comprises a first length and that may be attachably mounted on the flexible substrate. The conductive fabric component, in response to a direct or indirect application of external force to the flexible substrate, may stretch between the first length and a second length that is greater than the first length, and generate an electric parameter based at least in part on an amount of the applied external force. Other embodiments may be described and/or claimed.
